Problems solved by technology
Since 1970, the system and its corresponding identification method (Standard Seed box Screening Technique, SSST) have been continuously improved, which can identify the resistance of a large number of rice materials in a short time, and screen out better germplasm resources, but this method only relies on the final damage symptoms and performance of rice seedlings (number of yellow leaves or dead seedling rate) for grading, it is difficult to fully consider the influence of various factors, and there is a certain deviation in the evaluation of resistance

Embodiment
[0041] like Figure 1-6 As shown, a method for evaluating the resistance of rice to planthoppers based on radar maps includes the following specific steps:
[0042] 1) Obtain the statistical data of the insect resistance experiment, the statistical data of the avoidance experiment, the statistical data of the antibiotic resistance experiment, the statistical data of the pot experiment and the statistical data of the control group of rice respectively;
[0043] 2) Normalize the statistical data of the insect resistance experiment, the statistical data of the avoidance experiment, the statistical data of the antibiotic resistance experiment and the statistical data of the potting experiment obtained in step 1), and unify each index to [0, 6] Between, draw a radar chart;
[0044] 3) calculate the circumference evaluation vector V of evaluating the balance of each rice index according to the radar chart structure drawn in step 2),
[0045]
[0046] Among them, S is the area o...

The invention relates to the technical field of rice planting, and discloses a method for evaluating rice resistance to rice planthopper based on a radar map. The method comprises the following specific steps of 1) obtaining statistical data of insect resistance experiment, statistical data of repellent experiment, statistical data of antibiotic experiment and statistical data of pot experiment; 2) respectively normalizing statistical data of insect resistance experiment, statistical data of repellent experiment, statistical data of antibiotic experiment and statistical data of pot experimentobtained in step 1), unifying indicators to [0,6], and drawing the radar map; 3) according to a radar map structure drawn in step 2), calculating and evaluating a perimeter evaluation vector V of thebalance of each rice index; 4) using the perimeter evaluation vector V in step 3) to calculate an evaluation value Y which is a final evaluation result. The method contributes to the evaluation of insect resistance of excellent germplasm resources and the acquisition of rice materials resistant to the rice planthopper.
Description
technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a method for evaluating the resistance of rice to planthoppers based on a radar map. Background technique [0002] As a multivariate statistical chart, the radar chart can visualize multivariate data, and display the indicators of rice insect resistance, antibiotic resistance and repellency in it, which is convenient for intuitive and comprehensive analysis of its insect resistance. [0003] Radar charts are commonly used in the analysis of financial statements, but are relatively less used in the field of natural science. In the prior art, radar charts are used to evaluate and study the taste quality of rice, to evaluate the quality of cigarettes, and to display traditional Chinese medicine. The chemical composition of the plant is easy to distinguish its origin, and the radar map is used to visually classify the starch of plants, etc. These all show that the r...
