Embodiment Construction

[0016] The high-yield, high-quality cotton variety "Siyang 311" was used as the female parent, and the high-quality, high-yield, disease-resistant, and high-cloth cotton variety Siyang 263 (Simian No. 3) was used as the male parent to prepare a hybrid combination to obtain F 1 , F 1 Composite crossing with Gao Yifen's recurrent parent (Simian No. 3), and the resulting hybrid population self-crossed to obtain F 2 Generation; F 2 F 3 Generation, F 3 Obtained F by early generation selection identification 4 Generation, continuous selection to F 8 Generation, to obtain high-cloth, high-quality cotton varieties, and at the same time, continuous identification of disease nurseries and quality and resistance testing, combined with multiple generations of southern breeding, further accelerated the process of variety selection and breeding. "Simian No. 4" was bred in 1997. In the regional test of cotton varieties in Anhui Province from 1998 to 1999, the percentage of large samples...

Abstract

The invention discloses a method for cultivating high-quality, high-quality cotton varieties. A cotton variety (line) with high-quality, high-yield, and pest-resistant cotton is selected as the female parent, and the cotton variety (line) with a clothing content of about 43% and excellent comprehensiveness As the male parent, the high-cloth cotton variety (line) was used as the recurrent parent; the parents were paired and crossed, and the F with stable traits was selected. 1 A heterozygous population was obtained by recrossing the recurrent parent with a high-yield score; the heterozygous population was self-crossed to obtain F 2 F 3 to F 8 generation, and combined with southern multiplication plus generation to increase the pressure of spatio-temporal selection and speed up the breeding of varieties. The bred cotton varieties are high-yielding, high-quality, disease-resistant, and high-yielding, solving the technical problems of combining richness, resistance, and quality of cotton varieties, and having both long, fine and strong fiber quality, and promoting the progress of cotton technology and the development of cotton production in China.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method for cultivating new cotton varieties with high cotton content and high quality. Background technique [0002] The significance of cotton breeding work on the progress of cotton varieties is mainly reflected in the improvement of cotton yield, improvement of fiber quality and enhancement of resistance. my country has made remarkable achievements in high-cloth cotton breeding. Through the breeding methods such as introduction and trial, systematic breeding, hybrid breeding, distant hybridization, hybrid advantage utilization, mutation breeding, biotechnology and other breeding methods, it has successfully cultivated cotton that is suitable for use in different ecological regions in my country. Compared with foreign varieties such as "Daizimian 15" and "Daizimian 33B" introduced in the same period, the cotton varieties of Zhongmian, Simian, Lumian, and Xinlu series have significa...
