Embodiment Construction

[0017] Implementation procedure of the present invention is:

[0018] In the spring of the first year, Sumian 7 (a high-yield and high-resistance white cotton variety) was used as the female parent and Zong 23 (a brown cotton line introduced from the Cotton Research Institute of the Chinese Academy of Agricultural Sciences) was used as the male parent for artificial hybridization in Yancheng City, Jiangsu Province.

[0019] Selfing was carried out in Hainan in the first winter (F1 generation), and selfing was carried out in Jiangsu in the second spring (F2 generation), that is, through southern multiplication and multigeneration, a single plant of Zong 11-6 with basically stable traits was selected in the same year.

[0020] In the winter of the second year, the high-quality stigma-exposed line 68-3 was selected as the female parent, and the brown 11-6 was used as the male parent {68-3*[Su Mian No. 7*Zong 23)F3]} for further crossing in Hainan.

[0021] In the spring of...

Abstract

A method for selectively culturing the insect-resistance brown cotton with exposed stigma includes artificially crossing between Sumian No.7 as female parent and Zong No.23 as male parent, selfing twice to obtain Zong No.11-6, crossing with stigma-exposed cotton No.68-3 as female parent, selfing twice, choosing strong plant, and selfing to obtain the stigma exposed brown cotton DH101.

Description

Technical field [0001] The invention relates to a method for breeding colored cotton, in particular to a method for breeding brown cotton. Background technique [0002] At present, there are mainly two varieties of colored cotton, brown cotton and green cotton. In the process of planting colored cotton, no toxic substances such as chemical fertilizers and pesticides are used. The harm of preparations to human health is also conducive to protecting the environment and realizing people's dream of returning to nature, which is the development direction of cotton varieties in the 21st century. [0003] Since the early 1980s, some countries such as the United States have begun to plant colored cotton, but there is no report on the brown cotton varieties that can be directly adapted to China, and no literature has been retrieved that can be suitable for the selection of brown cotton varieties that are planted in China. reports. [0004] In the late 1980s, my country began to bre...
