Problems solved by technology

The more traits used for phenotypic evaluation, the larger the amount of data, and the more reliable the results, but it is often difficult to achieve simple, batch, direct and intuitive goals due to time, human, financial and other factors in preliminary analysis

Embodiment 1

[0030] 1. Investigation of phenotypic traits:

[0031] Meter rulers, micro-scale calipers and balances are used to measure the values ​​of traits. The volume measurement unit is centimeters except for the diameter of the main shoot, which is millimeters, and the weight measurement unit is grams. The nine phenotypic traits of kale were investigated: plant height (X 1 ), development (X 2 ), number of leaves (X 3 ), leaf weight (X 4 ), main shoot height (X 5 ), main stem diameter (X 6 ), the number of side branches (X 7 ), main shoot weight (X 8 ) and plant weight (X 9 ).

[0032] 2. Methods and formulas for conversion and reduction of phenotypic traits into volume, weight and density

[0033] 2.1 Volume ratio of main shoots:

[0034] The plant height is the height from the plant ground to the top of the plant when viewed from the side, and the spread is the longest distance and the widest distance from the plane where the leaves of the plant are located when viewed fro...

Abstract

The invention provides a physical index analysis method for phenotypic diversity of cabbage mustard, and relates to the technical field of phenotypic diversity analysis. According to the method, physical information of phenotypic data is deeply mined; relatively complicated and independent botanical trait evaluation is converted into simple physical evaluation; plant phenotypic characteristic information is re-mined from the perspective of physics; that is, nine botanical traits such as plant height, development degree, leaf number, leaf weight, main bolting stem length, main bolting thickness, main bolting weight, single plant weight and branch number are converted into three physical attribute indexes such as main bolting volume ratio, bolting leaf weight ratio and density, and analyzing, comparing and evaluating of phenotypic diversity are carried out according to physical attributes. The method has the advantages of simplicity, batch, directness and intuition, is suitable for preliminary analysis, comparison and evaluation of a large number of cabbage mustard variety resources, and the purposes of saving a large amount of time, manpower, financial resources and material resources, deepening perceptual knowledge, reducing a phenotypic diversity research threshold and objectively evaluating phenotypic diversity are achieved.

Description

technical field [0001] The invention belongs to the technical field of phenotypic diversity analysis, and in particular relates to a method for analyzing phenotypic diversity by utilizing physical properties of kale. Background technique [0002] Chinese kale is a one-two-year-old herbaceous plant of the genus Brassica in the family Brassicaceae. It uses flowering shoots and young leaves as edible organs. It is crisp and tender, rich in nutrition and unique in flavor, and is deeply loved by consumers. Chinese kale is mainly distributed in Guangdong, Guangxi, Fujian and other places, especially in Guangdong where it is most commonly cultivated. It is one of the main characteristic vegetables in South China and an important foreign exchange earning vegetable for export. The main agronomic traits of kale were significantly different, such as the number of leaves, plant height, stem diameter, economic yield, stem / leaf value, first side branch position, petiole color, petal color...
