Problems solved by technology

[0005] At present, the leaves of the parents of the three-line hybrids and the three-line hybrids are all conventional types of green leaves. The purity of the hybrids does not have any appearance markers, which can be visually distinguished by naked eyes. Due to the profit-driven cotton hybrid seeds in the market, adulteration is false and substandard. The frequent occurrence of overfilling makes the rights and interests of breeders unable to be guaranteed, and at the same time brings irreparable losses to seed management enterprises and cotton farmers

Embodiment 1

[0025] Example 1, the acquisition of a sterile line with purple-red marker traits

[0026] 1. Breeding of CMS lines with purple-red marker traits

[0027] 1. In the experimental field of Handan Academy of Agricultural Sciences in July 2006, the magenta-marked line 27005 was used as the male parent, and the insect-resistant CMS line Han 6208A was used as the female parent, and the purple-red marked trait was transferred to the insect-resistant CMS line Han In 6208A, the 27005 line with purple marker traits was used as the recurrent parent. From 2007 to 2009, more than 6 times of cross breeding and screening were carried out in the experimental fields of Hainan and Handan Academy of Agricultural Sciences. An excellent cytoplasmic male insect-resistant sterile line Han 6208 Fuchsia A with fuchsia marker traits.

[0028] 2. In the experimental field of Handan Academy of Agricultural Sciences in July 2006, the magenta-marked line 27005 was used as the male parent, and the insect-r...

Embodiment 2

[0058] Example 2, Three-line Hybrid Cotton Combination Matching with Magenta Marker Characters

[0059] Set up the following 3 hybrid combinations:

[0060] 1. In 2011, the female parent of Han 6208 Fuchsia A with fuchsia-marked traits was crossed with the conventional restorer line Han R251 as male parent to obtain insect-resistant three-line hybrids with fuchsia-marked traits.

[0061] 2. In 2011, Han 6208 Fuchsia A with fuchsia-marked traits was used as the female parent and the conventional restorer line Han R174 was used as the male parent to obtain insect-resistant three-line hybrids with fuchsia-marked traits.

[0062] 3. In 2011, Han 6208 Fuchsia A with fuchsia-marked traits was used as the female parent and the conventional restorer line 18R was used as the male parent to obtain insect-resistant three-line hybrids with fuchsia-marked traits.

[0063] From 2012 to 2016, the hybrid combinations assembled for many years participated in the self-set production ratio test...

Abstract

The invention discloses a seed production method of three-line hybrid cotton marked with purple red. In the present invention, the purple-red marker trait is transferred to the cytoplasmic male insect-resistant sterile line of upland cotton, and the insect-resistant three-line hybrid with the purple-red marker trait is produced by crossing the restorer line with it, which can be obtained at the cotyledon stage Early identification of purity, compared with the traditional identification of comprehensive traits during the growth period of cotton, greatly shortens the identification period, better solves the problem of purity identification of three-line hybrids in production, and makes the three-line hybrids better in production. Play a role.

Description

technical field [0001] The invention relates to the field of crop breeding, in particular to a seed production method of three-line hybrid cotton marked with purple red. Background technique [0002] There are more than 30 kinds of crops using heterosis in the world, such as maize and three-line hybrid rice have made great achievements in its application. Human beings have studied cotton heterosis for more than 100 years. According to the "American Cotton Production Research Association Papers" report, the heterosis (HP) range of lint yield is 4-33%, with an average of 15-27%; was 6.6%. Cotton heterosis research has always been highly valued by major cotton-producing countries. my country has carried out hybrid cotton research since the 1960s, and bred a large number of hybrid cotton varieties for large-scale promotion and application in production, such as Zhong 29, Lumian 15 , Hanza 98-1, Hanza 301, etc. [0003] At present, the production of cotton hybrids mainly adopt...
