Description

Technical Field

[0001] This invention relates to the field of map construction technology, specifically a method for constructing a data map of tea germplasm resources. Background Technology

[0002] Tea germplasm resource data mainly includes genetic information, quantity, distribution, and utilization of planting resources. Specifically, it can be divided into: 1. Genetic data, which includes whole-genome genetic variation maps and molecular marker data; 2. Planting data, which reflects the distribution and quantity of ancient tea trees; 3. Application data, which involves tea variety breeding, pest and disease control, and ecological management. Data mapping is a technical tool that systematically presents data relationships, structures, and categories in a visual way. Its core function is to reveal the correlation between data and support analytical decision-making.

[0003] Existing methods for constructing data maps of tea germplasm resources typically use the 13 stages of tea production as the framework for map construction. After data collection and feature extraction, a database is established, and the entities, relationships, and attributes of the tea germplasm ontology and secondary maps are built. Finally, data is extracted to obtain triples and stored. While this improved method can extract unstructured data features from tea data and improve data extraction efficiency during processing, the map construction lacks depth. It only constructs a planar relationship network of the tea production process within the tea plantation. In practical use, it cannot capture the transmission and genetic relationships between tea plants within the map. This results in an inability to effectively obtain information on the regional distribution, genetic diversity, and correlations between different varieties of tea plants, leading to a low amount of data acquisition for users, such as in publicly available... Patent application CN114780740A discloses a method for constructing a tea knowledge graph. This method identifies named entities in the tea industry, constructs an ontology using the experience of tea experts, and automatically extracts unstructured data features by combining a bidirectional long short-term memory network and a conditional random field model, thereby improving knowledge extraction efficiency. However, other improvements for constructing tea germplasm resource data graphs are usually improvements on planar graph construction, which still cannot solve the problem of insufficient three-dimensionality in graph construction and the inability to obtain transmission and genetic relationships between tea trees in the graph. This results in the inability to effectively obtain information on the regional distribution, genetic diversity, and correlations between different varieties of tea trees through the graph, leading to a low amount of data acquisition for users. Therefore, it is necessary to improve the existing methods for constructing tea germplasm resource data graphs. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in the prior art by proposing a method for constructing a data map of tea germplasm resources. This method addresses the issue that existing methods for constructing data maps of tea germplasm resources lack three-dimensionality and fail to capture the transmission and genetic relationships between tea trees. Consequently, the map cannot effectively capture information about the regional distribution, genetic diversity, and inter-variety relationships of tea trees, resulting in low data acquisition for users.

[0005] To achieve the above objectives, this application provides a method for constructing a data map of tea germplasm resources, comprising the following steps:

[0006] Existing tea germplasm resource data were analyzed, and germplasm data transmission data and germplasm genetic data were obtained based on the analysis results; a basic geographic map was established based on the tea germplasm resource data.

[0007] Based on the germplasm data transmission data and germplasm genetic data, the basic geographic map is filled in, and the filled basic geographic map is recorded as the germplasm data map; the transmission genetic map of each tea tree in the germplasm data map is obtained;

[0008] Based on the genetic transmission maps of all tea trees in the germplasm data map, we obtained the tea trees that could be associated and their corresponding association parameters, and then drew the association lines of the tea trees in the germplasm data map.

[0009] Furthermore, existing tea germplasm resource data were analyzed, and germplasm data transmission data and germplasm genetic data were obtained based on the analysis results, including:

[0010] For any tea tree recorded in the tea germplasm resource data: the geographical location corresponding to the origin of the tea tree in the tea germplasm resource data is recorded as the origin of the tea tree, and the geographical location where the tea tree was spread when it was promoted is recorded as the spread location of the tea tree; tea trees that have a genetic relationship with the tea tree recorded in the tea germplasm resource data are recorded as the direct related plants of the tea tree, and closely related plants of the tea tree recorded in the tea germplasm resource data are recorded as the indirect related plants of the tea tree.

[0011] The data on the origin and transmission locations of all tea trees in the tea germplasm resource data are recorded as germplasm data transmission data; the data on the direct and indirect related plants of all tea trees in the tea germplasm resource data are recorded as germplasm genetic data.

[0012] Furthermore, establishing a basic geographic map based on tea germplasm resource data includes:

[0013] Obtain all geographical locations of tea trees from existing tea tree germplasm resource data and record them as tea tree locations. The tea tree locations include the geographical locations of all indirect related plants of all tea trees, the origin of the tea trees, and the transmission locations of the tea trees. Mark all tea tree locations on a map and record the map containing all tea tree locations as a tea tree distribution map. Use AI to obtain the smallest circle that encloses all tea tree locations on the tea tree distribution map and record the center of the smallest circle as the distribution center.

[0014] Establish a spatial rectangular coordinate system, denoted as the tea tree germplasm coordinate system, where the units of the X-axis, Y-axis, and Z-axis of the tea tree germplasm coordinate system are all meters; align the distribution center of the tea tree distribution map with the origin of the tea tree germplasm coordinate system, and place the tea tree distribution map proportionally within the XY plane of the tea tree germplasm coordinate system.

[0015] Furthermore, establishing a basic geographic map based on tea germplasm resource data also includes:

[0016] For any tea tree location marked in the tea tree germplasm coordinate system, obtain the altitude of the geographical location corresponding to the tea tree location and record it as z1. Update the coordinates of the tea tree location in the tea tree distribution map in the tea tree germplasm coordinate system to (x1, y1, z1), where (x1, y1, 0) are the coordinates of the tea tree location after the tea tree distribution map is placed proportionally in the tea tree germplasm coordinate system.

[0017] The coordinates of all tea tree locations in the tea tree germplasm coordinate system are updated, and the updated tea tree distribution map in the tea tree germplasm coordinate system is recorded as the basic geographic map.

[0018] Furthermore, the basic geographic map is filled in based on germplasm data transmission data and germplasm genetic data, and the filled basic geographic map is recorded as a germplasm data map, including:

[0019] For any tea tree recorded in the tea germplasm resource data: For any tea tree transmission location recorded in the germplasm data transmission data, connect the tea tree origin location in the basic geographic map with the tea tree transmission location, and record the connection as the tea tree propagation path.

[0020] Mark all propagation paths corresponding to all tea trees in the basic geographic map, and record the basic geographic map at this time as the transmission geographic map.

[0021] Furthermore, the process of filling in the basic geographic map based on germplasm data transmission data and germplasm genetic data, and recording the filled basic geographic map as a germplasm data map, also includes:

[0022] For any tea tree recorded in the tea tree germplasm resource data: the coordinates corresponding to the origin of the tea tree in the transmission geographic map are marked as (x0, y0, z0), and the point with coordinates (x0, y0, -z0) in the tea tree germplasm coordinate system is recorded as the genetic source point of the tea tree. (x0, y0, z0) and (x0, y0, -z0) are connected by a dashed line and recorded as the genetic association line.

[0023] For any directly related plant α and indirectly related plant β of tea trees, the point symmetrical about the XY plane corresponding to the tea tree origin of the directly related plant α in the tea tree germplasm coordinate system is denoted as the direct relationship pair point; the point symmetrical about the XY plane corresponding to the tea tree origin of the indirectly related plant β in the tea tree germplasm coordinate system is denoted as the indirect relationship pair point.

[0024] Furthermore, the process of filling in the basic geographic map based on germplasm data transmission data and germplasm genetic data, and recording the filled basic geographic map as a germplasm data map, also includes:

[0025] The line connecting the genetic source point of a tea plant to its direct relative is called the direct genetic line, and the line connecting the genetic source point of a tea plant to its indirect relative is called the indirect genetic line.

[0026] Within the tea plant germplasm coordinate system, obtain all direct and indirect genetic lines corresponding to all tea plants, and record the map at this time, which consists of the transmission geographic map, all genetic association lines, and the direct and indirect genetic lines of all tea plants, as the germplasm data map.

[0027] Furthermore, obtaining the transmission genetic map of each tea plant in the germplasm data map includes:

[0028] For any tea tree recorded in the tea germplasm resource data: the map consisting of all the propagation paths, genetic association lines, direct genetic lines and indirect genetic lines corresponding to the tea tree is recorded as the transmission genetic map of the tea tree.

[0029] Obtain the transmission genetic map corresponding to all tea trees recorded in the tea tree germplasm resources, and record the position of tea tree that is not in any transmission genetic map in the germplasm data map as an independent germplasm position.

[0030] Furthermore, based on the genetic transmission maps of all tea trees in the germplasm data map, the associative tea trees and their corresponding association parameters are obtained, and tea tree association lines are drawn in the germplasm data map, including:

[0031] For any two transgenetic maps T and R that have overlapping regions in the transgenetic maps corresponding to all tea trees: the tea trees corresponding to transgenetic maps T and R are mutually recorded as associatable tea trees, and the map association algorithm is used to obtain the association parameters of the tea trees corresponding to transgenetic maps T and R.

[0032] Graph association algorithms include: Wherein, when the overlapping regions of the genetic map T and the genetic map R are only located in the region of the positive half-axis of the Z-axis, L0 is the length of the line segment corresponding to the overlapping region of the genetic map T and the genetic map R, L1 is the length of the non-dashed line in the genetic map T within the positive half-axis of the Z-axis, and L2 is the length of the non-dashed line in the genetic map R within the positive half-axis of the Z-axis. F1 at this time is recorded as the tea tree association parameter.

[0033] When the overlapping regions of the genetic transmission map T and the genetic transmission map R are located only in the negative half-axis of the Z-axis, D0 is the length of the line segment corresponding to the overlapping region of the genetic transmission map T and the genetic transmission map R, D1 is the length of the non-dashed line connecting the genetic transmission map T within the negative half-axis of the Z-axis, and D2 is the length of the non-dashed line connecting the genetic transmission map R within the negative half-axis of the Z-axis. F2 at this time is recorded as the tea tree association parameter.

[0034] When there is an overlapping region between the genetic map T and the genetic map R on both the positive and negative Z-axis, F3 is recorded as the tea tree association parameter based on the acquisition methods of F1 and F2.

[0035] Furthermore, based on the genetic transmission maps of all tea trees in the germplasm data map, obtaining associatable tea trees and their corresponding association parameters, and drawing tea tree association lines in the germplasm data map also includes:

[0036] Obtain all tea trees that can be associated in the tea tree germplasm resource data, and obtain the tea tree association parameters corresponding to each group of tea trees that can be associated; for any tea tree γ: in the germplasm data map, the tea tree source area corresponding to the tea tree that is mutually associated with tea tree γ is recorded as the associated source area;

[0037] The tea tree origin of tea tree γ is sequentially connected to all associated origins, and the lines are denoted as tea tree association lines. The tea tree association parameters corresponding to the tea trees at both ends of each tea tree association line are marked.

[0038] The beneficial effects of this invention are as follows: This application first analyzes existing tea tree germplasm resource data and obtains germplasm data transmission data and germplasm genetic data based on the analysis results; a basic geographic map is established based on the tea tree germplasm resource data; then, the basic geographic map is filled in based on the germplasm data transmission data and germplasm genetic data, and the filled basic geographic map is recorded as the germplasm data map. The advantage of this is that by establishing the basic geographic map, the geographical locations corresponding to all tea trees in the tea tree germplasm resource data can be effectively marked, and based on the actual altitude, the obtained basic geographic map is more three-dimensional, making it easier for users to intuitively obtain the geographical location corresponding to each tea tree when using the map; by using the germplasm data transmission data and germplasm genetic data to fill in the basic geographic map and obtain the germplasm data map, users can obtain the transmission and genetic relationships between tea trees based on the spread of each tea tree from its place of origin and its genetic characteristics, thereby increasing the amount of data obtained by users when using the map and optimizing the user experience.

[0039] This application also obtains the genetic transmission map of each tea tree in the germplasm data map; finally, based on the genetic transmission maps of all tea trees in the germplasm data map, it obtains the associative tea trees and their corresponding association parameters, and plots tea tree association lines in the germplasm data map. The advantage of this is that by obtaining the genetic transmission map of tea trees and further obtaining tea tree association lines, users can easily obtain all the data corresponding to the same tea tree, while also obtaining the association between tea trees based on the tea tree association lines. This enables users to effectively obtain data on the regional distribution, genetic diversity, and association between different varieties of tea trees through the germplasm data map, thereby increasing the amount of data obtained by users.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1, please refer to Figure 1 As shown, this application provides a method for constructing a data map of tea germplasm resources, including the following steps:

[0046] Step S1: Analyze existing tea germplasm resource data, and obtain germplasm data transmission data and germplasm genetic data based on the analysis results; establish a basic geographic map based on the tea germplasm resource data;

[0047] Step S1 includes: Step S101, for any tea tree recorded in the tea tree germplasm resource data: the geographical location corresponding to the origin of the tea tree in the tea tree germplasm resource data is recorded as the origin of the tea tree, and the geographical location where the tea tree was spread when it was promoted is recorded as the spread location of the tea tree; the tea trees that have a genetic relationship with the tea tree recorded in the tea tree germplasm resource data are recorded as the direct related plants of the tea tree, and the closely related plants of the tea tree recorded in the tea tree germplasm resource data are recorded as the indirect related plants of the tea tree;

[0048] In the specific implementation process, for example, if the tea tree obtained in a data analysis is Longjing 43, and the origin of Longjing 43 recorded in the tea tree germplasm resource data is located in the experimental tea garden at the foot of Wuyun Mountain in Hangzhou, then the geographical location corresponding to the foot of Wuyun Mountain in Hangzhou can be regarded as the origin of Longjing 43 tea trees. The promotion area of ​​Longjing 43 can be marked according to the actual location recorded in the actual tea tree germplasm resource data, such as tea producing areas in Zhejiang, Anhui, Hunan and Jiangxi.

[0049] Since the parent of Longjing 43 is the Longjing population, the tea trees in the Longjing population recorded in the tea germplasm resource data that are genetically related to Longjing 43 can be recorded as directly related plants. Since the closely related plants of Longjing 43 mainly include its wild closely related populations, that is, the common ancestors of small-leaf tea varieties such as tea variant and large-leaf tea varieties such as Assam variant, the wild closely related populations of Longjing 43 recorded in the tea germplasm resource data can be recorded as indirectly related plants of Longjing 43.

[0050] Step S102: Record the data of the origin and transmission location of all tea trees in the tea germplasm resource data as germplasm data transmission data; record the data of the direct and indirect related plants of all tea trees in the tea germplasm resource data as germplasm genetic data.

[0051] Step S103: Obtain all geographical locations of tea trees in the existing tea tree germplasm resource data and record them as tea tree locations. The tea tree locations include the geographical locations of all indirect related plants of all tea trees, the origin of tea trees, and the transmission locations of tea trees. Mark all tea tree locations on the map and record the map containing all tea tree locations as the tea tree distribution map. Use AI to obtain the smallest circle that encloses all tea tree locations in the tea tree distribution map and record the center of the smallest circle as the distribution center.

[0052] In the specific implementation process, since the geographical locations of tea trees recorded in the tea germplasm resource data may include the geographical locations of tea trees of foreign varieties, the number of tea tree locations should be greater than or equal to the number of geographical locations of all tea tree origins + the number of geographical locations of the corresponding tea tree transmission sites + the number of geographical locations of indirect related plants of the tea tree.

[0053] Step S104: Establish a spatial rectangular coordinate system and denote it as the tea tree germplasm coordinate system. The units of the X-axis, Y-axis and Z-axis of the tea tree germplasm coordinate system are all meters. Align the distribution center of the tea tree distribution map with the origin of the tea tree germplasm coordinate system and place the tea tree distribution map proportionally in the XY plane of the tea tree germplasm coordinate system.

[0054] Step S105: For any tea tree location marked in the tea tree germplasm coordinate system, obtain the altitude in the geographical location corresponding to the tea tree location and record it as z1. Update the coordinates of the tea tree location in the tea tree distribution map in the tea tree germplasm coordinate system to (x1, y1, z1), where (x1, y1, 0) are the coordinates of the tea tree location after the tea tree distribution map is placed proportionally in the tea tree germplasm coordinate system.

[0055] In the specific implementation process, for example, during a data analysis, if the altitude of the geographical location of the Longjing 43 tea tree's transmission site is 20m, then the value of z1 can be recorded as 20, and the coordinates corresponding to the Longjing 43 tea tree's transmission site can be updated to (x1, y1, 20). By updating the coordinates of all tea tree locations in the tea tree germplasm coordinate system, the obtained basic geographic map can be made more three-dimensional, making it easier for users to intuitively obtain the geographical location corresponding to each type of tea tree when using the map.

[0056] Step S106: Update the coordinates of all tea tree locations in the tea tree germplasm coordinate system, and record the updated tea tree distribution map in the tea tree germplasm coordinate system as the basic geographic map.

[0057] Step S2: Fill the basic geographic map based on the germplasm data transmission data and germplasm genetic data respectively, and record the filled basic geographic map as the germplasm data map; obtain the transmission genetic map of each tea tree in the germplasm data map;

[0058] Step S2 includes: Step S201, for any tea tree recorded in the tea tree germplasm resource data: for any tea tree transmission location recorded in the germplasm data transmission data, connect the tea tree origin location in the basic geographic map with the tea tree transmission location, and record the connection as the tea tree propagation path.

[0059] Step S202: Mark all propagation paths corresponding to all tea trees in the basic geographic map, and record the basic geographic map at this time as the transmission geographic map;

[0060] In the specific implementation process, for example, during a data analysis, the basic geographical map obtained within the tea tree germplasm coordinate system is as follows: Figure 2 As shown in QQ1, points TT1 and TT2 represent the origin of two tea trees, points RR1 to RR3 represent the transmission sites of the tea tree corresponding to point TT1, and points RR4 and RR5 represent the transmission sites of the tea tree corresponding to point TT2. The resulting transmission geographic map after marking the transmission paths is as follows: Figure 2 As shown in QQ2.

[0061] Step S203: For any tea tree recorded in the tea tree germplasm resource data: mark the coordinates of the tea tree origin in the transmission geographic map as (x0, y0, z0), and mark the point with coordinates (x0, y0, -z0) in the tea tree germplasm coordinate system as the genetic source point of the tea tree. Connect (x0, y0, z0) and (x0, y0, -z0) with a dashed line and mark it as the genetic association line.

[0062] Step S204: For any directly related plant α and indirectly related plant β of tea trees, the points symmetrical about the XY plane corresponding to the tea tree origin of the directly related plant α in the tea tree germplasm coordinate system are recorded as the direct relationship pair points; the points symmetrical about the XY plane corresponding to the tea tree origin of the indirectly related plant β in the tea tree germplasm coordinate system are recorded as the indirect relationship pair points.

[0063] In the specific implementation process, for example, in a data analysis, the indirect relationship plant β is a wild closely related plant in Longjing 43, and the point corresponding to the tea tree source is (440,410,32). Then, by obtaining the point symmetrical about the XY plane, the indirect relationship pair point is (440,410,-32).

[0064] Step S205: The line connecting the genetic source point of the tea tree to the point of direct relationship is recorded as the direct genetic line, and the line connecting the genetic source point of the tea tree to the point of indirect relationship is recorded as the indirect genetic line.

[0065] Step S206: Obtain all direct and indirect genetic lines corresponding to all tea trees in the tea tree germplasm coordinate system, and record the map consisting of the transmission geographic map, all genetic association lines, and the direct and indirect genetic lines of all tea trees as the germplasm data map.

[0066] In the specific implementation process, by acquiring germplasm data maps, the regional distribution and genetic distribution of all tea trees in the tea germplasm resource data can be integrated and displayed, thereby improving the information acquisition efficiency for users when using the maps.

[0067] Step S207: For any tea tree recorded in the tea germplasm resource data: record the map consisting of all the propagation paths, genetic association lines, direct genetic lines and indirect genetic lines corresponding to the tea tree as the transmission genetic map of the tea tree.

[0068] In the specific implementation process, for example, during a data analysis, the genetic map of Longjing 43 obtained is as follows: Figure 3 As shown, point UU1 is the origin of Longjing 43 tea trees, straight lines LJ1 to LJ4 are all propagation paths, dashed line CY is the genetic association line, ZC1 and ZC2 are direct genetic lines, and JC1 and JC2 are indirect genetic lines.

[0069] Step S208: Obtain the transmission genetic map corresponding to all tea trees recorded in the tea tree germplasm resources, and record the position of tea tree that is not in any transmission genetic map in the germplasm data map as an independent germplasm position.

[0070] Step S3: Based on the genetic transmission maps of all tea trees in the germplasm data map, obtain the tea trees that can be associated and the corresponding tea tree association parameters, and draw the tea tree association lines in the germplasm data map;

[0071] Step S3 includes: Step S301, for any two transmission genetic maps T and R with overlapping regions in the transmission genetic maps corresponding to all tea trees: the tea trees corresponding to the transmission genetic map T and the transmission genetic map R are mutually recorded as associatable tea trees, and the association parameters of the tea trees corresponding to the transmission genetic map T and the transmission genetic map R are obtained using the map association algorithm.

[0072] Step S302, the graph association algorithm includes: Wherein, when the overlapping regions of the genetic map T and the genetic map R are only located in the region of the positive half-axis of the Z-axis, L0 is the length of the line segment corresponding to the overlapping region of the genetic map T and the genetic map R, L1 is the length of the non-dashed line in the genetic map T within the positive half-axis of the Z-axis, and L2 is the length of the non-dashed line in the genetic map R within the positive half-axis of the Z-axis. F1 at this time is recorded as the tea tree association parameter.

[0073] In specific implementation, for example, during a data analysis, it was found that the genetic transmission patterns of Longjing 43 and Laochapeng overlapped, and only existed in the region of the positive half-axis of the Z-axis. Through data acquisition, the line segment lengths corresponding to L0, L1, and L2 were found to be 100, 500, and 400, respectively. Then, through calculation, F1 was found to be 0.45, that is, the tea tree association parameter was 0.45. By obtaining the tea tree association parameter, the strength of the association between the two teas with overlapping genetic transmission patterns can be judged by the sum of the ratio of the overlapping length of the line segments in the same region to the total length. The larger the tea tree association parameter, the longer the overlapping length in the genetic transmission patterns of the two teas, that is, the stronger the association.

[0074] Step S303: When the overlapping regions of the genetic transmission map T and the genetic transmission map R are only located in the negative half-axis of the Z-axis, D0 is the length of the line segment corresponding to the overlapping region of the genetic transmission map T and the genetic transmission map R, D1 is the length of the non-dashed line in the genetic transmission map T within the negative half-axis of the Z-axis, and D2 is the length of the non-dashed line in the genetic transmission map R within the negative half-axis of the Z-axis. F2 at this time is recorded as the tea tree association parameter.

[0075] Step S304: When there is an overlapping region between the genetic map T and the genetic map R on both the positive and negative half-axis of the Z-axis, based on the acquisition methods of F1 and F2, the F3 at this time is recorded as the tea tree association parameter.

[0076] Step S305: Obtain all tea trees that can be associated in the tea tree germplasm resource data, and obtain the tea tree association parameters corresponding to each group of tea trees that can be associated; For any tea tree γ: In the germplasm data map, the tea tree source area corresponding to the tea tree that is mutually associated with tea tree γ is recorded as the associated source area;

[0077] Step S306: Connect the tea tree source of tea tree γ to all the associated source in sequence, and record them as tea tree association lines. Mark the tea tree association parameters corresponding to the tea trees at both ends of each tea tree association line.

[0078] In the specific implementation process, by obtaining tea tree correlation lines and marking tea tree correlation parameters, users can intuitively obtain tea trees that are related to the queried tea tree and the numerical values ​​that can reflect the correlation when using the map to query tea trees. This makes it easier for users to effectively obtain data corresponding to the correlation between different tea tree varieties and increase the amount of data obtained by users.

[0079] Example 2, please refer to Figure 4 As shown, Figure 4A schematic diagram of an electronic device is provided, which may include a processor, a communication interface, a memory, and a communication bus. The processor, communication interface, and memory communicate with each other via the communication bus. The memory stores computer-readable instructions, and the processor can call these instructions. When the processor executes a computer-readable instruction, it performs steps as described in a method for constructing a tea germplasm resource data map, to achieve the following functions: First, existing tea germplasm resource data is analyzed, and germplasm data transmission data and germplasm genetic data are obtained based on the analysis results; a basic geographic map is established based on the tea germplasm resource data; then, the basic geographic map is filled with the germplasm data transmission data and germplasm genetic data, and the filled basic geographic map is recorded as the germplasm data map; the transmission genetic map of each tea tree in the germplasm data map is obtained; finally, based on the transmission genetic maps of all tea trees in the germplasm data map, associative tea trees and their corresponding association parameters are obtained, and tea tree association lines are drawn in the germplasm data map.
