Embodiment 1

[0023] Example 1 Using the following method, the standard hybrid A1 hybrid cotton was bred by the Plant Protection Research Institute of the Henan Academy of Agricultural Sciences, and was approved by the Henan Provincial Variety Approval Committee in 2001:

[0024] (1) Breed and select cotton pure line variety material Y with super chicken feet and leaves without pigment glands 2-2 as a paternal parent, see figure 1 ;

[0025] (2) Breed and select a number of conventional cotton pure line varieties YmR with good agronomic traits and high yield, good fiber quality, and a certain complementarity with the male parent traits. 1 As a parent, see figure 2 ;

[0026] (3) The method of artificial tasseling and pollination is used to prepare hybrids in multiple combinations, and the optimal combination standard hybrid A1 is selected through routine field experiments;

[0027] (4) The follow-up method is the same as the breeding method of common cotton varieties.

Abstract

The invention relates to a cotton hybrid breeding method utilizing a double labeling method. Doubling labeling materials including a cotton chick-claw leaf and a pigment gland are selected and used to perform hybrid cotton breeding. A cotton F1 generation hybrid bred by the method has remarkable characteristic differences from those of a male parent and a female parent and has remarkable labeling characteristics during a whole growth period, seed purity is identified easily, the problem of purity identification of the cotton hybrid is effectively solved, the production quality of the cotton hybrid can be controlled simply, conveniently and effectively, the production cost is reduced, and the seed production area can be expanded at any time according to the requirements. The seed production method can prevent cotton hybrids which are forged and fake and poor in purity from entering into the market, provides technical support and protection for legitimate rights and interests of producers, operators and cotton growers, and has high application value for promoting healthy development of a cotton seed industry.

Description

technical field [0001] The invention relates to a breeding method, in particular to a cotton hybrid breeding method by double-marking method of chicken feet and pigment glands. Background technique [0002] With the advancement of science and technology and the development of agricultural production technology, more and more excellent varieties have made significant contributions to high and stable agricultural yields. Cotton hybrids have excellent traits such as high yield, high quality, insect resistance, and disease resistance. The application of cotton hybrids plays an important role in improving the yield level of cotton in my country. At present, the planting area of ​​hybrid cotton in my country is more than 1 million hectares. More than 90% of cotton hybrids used in production are selected and produced by artificial emasculation and pollination. [0003] In the process of cotton hybrid production, operators or intermediary organizations usually arrange production t...
