Embodiment Construction

[0026] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 1 As shown, the embodiment of the present invention provides a kind of breeding method of high-yield and high-quality multi-resistant cotton, comprising the steps of:

[0028] S1. Select the cotton variety carrying the target trait as the parent group, and screen out the parents with complementary advantages for hybridization to obtain the F1 generation group;

[0029] S11. Use the web crawler module to crawl the corresponding cotton parent group information based on the target traits;

[0030] S12, using the BP neural network to realize the grouping of parental groups based on the preset principle of complementary advant...

Abstract

The invention discloses a breeding method of high-yield high-quality multi-resistance cotton. The breeding method comprises the following steps: S1, selecting a cotton variety carrying target traits as a parent group, screening out parents being in complementary in advantages, and performing hybridizing to obtain an F1 generation group; S2, performing genetic similarity analysis on the F1 generation group obtained in the step S2 by utilizing an SSR marking method based on a molecular marker of a target character, and screening out F1 single plants carrying target character genes; and S3, performing artificial simulation planting land environment training, and screening out a strain with the highest yield. Through combination of SSR molecular marking and artificial simulation planting landenvironment training, the breeding speed for germplasm resource innovation is greatly increased, and besides, varieties suitable for different planting environments can be screened out at the same time.

Description

technical field [0001] The invention relates to the field of cotton breeding, in particular to a breeding method for high-yield, high-quality, multi-resistant cotton. Background technique [0002] Cotton is an important economic crop and occupies an important position in the development of the national economy. The three major cotton production areas in my country, including many different sub-regions, have complex ecological conditions and diverse planting systems. [0003] For example, the climate and ecological conditions are extremely unstable from year to year, and the frequency of natural disasters is relatively high. Drought, disease, especially low temperature or rainy and little light in the late growth period of cotton cause cotton to fall off and rotten bolls, which have an important impact on cotton production and seriously affect the yield. quality. Cotton varieties have the problems of delayed development, late maturity or premature senility, low and unstable...
