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

[0031] 1. Investigation of phenotypic traits:

[0032] Use meter ruler, micro-scale caliper and balance to measure the value of characters. The volume measurement unit is centimeter except the main sprout diameter is millimeter, and the weight measurement unit is gram. The 9 phenotypic traits of leaf mustard were investigated: plant height (X 1 ), development degree (X 2 ), the number of leaves (X 3 ), leaf weight (X 4 ), the height of the main sedge (X 5 ), diameter of main sprouts (X 6 ), the number of side branches (X 7 ), the main sedge weight (X 8 ) and plant weight (X 9 ).

[0033] 2. Methods and formulas for transformation and reduction of phenotypic traits to volume, weight and density

[0034] 2.1 Volume ratio of main sprouts:

[0035] The plant height is the height from the ground of the plant to the top of the plant when viewed from the side, and the degree of development is the longest distance and the widest distance from the side where the leaves of the...

Abstract

The invention provides a physical index analysis method for phenotypic diversity of leaf mustard, and relates to the technical field of phenotypic diversity analysis. According to the invention, phenotypic data physical information 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 leaf 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, in particular to a physical index analysis method of leaf mustard phenotype diversity. Background technique [0002] Leaf mustard belongs to the Brassica genus of the Cruciferae family, the center of origin is in China, and the natural resources are very rich. In the breeding of new varieties, the biological diversity of germplasm resources is the material basis of breeding work, and the key to improving varieties is the effective use of germplasm resources. The characteristics and rational classification of leaf mustard germplasm resources are one of the prerequisites for selecting parents, transforming target materials and improving breeding efficiency. There are obvious differences in the main agronomic characters of leaf mustard, plant height, plant width, number of leaves, leaf length, leaf width, petiole length, petiole width, petiole thickness, leaf folds, cracks, le...
