Seletive breeding method of new green cotton variety

Abstract

The selective breeding method of new green cotton variety includes artificial crossbreeding and twice selfing with Xiangmian-16 cotton variety as female parent and Lu-1 green cotton variety as male parent to breed selectively Lu11-6 green cotton variety; artificial crossbreeding and twice selfing with Xiangmian68-3 cotton variety as female parent and Lu11-6 green cotton variety as male parent; selecting high quality plants in field and selfing to purify so as to obtain the new green cotton variety Lu-89. The green cotton variety Lu-89 has excellent fiber quality, high industrial spinnability, dark color, high color fast and high yield.

Description

technical field [0001] The invention relates to a method for breeding new green cotton varieties. Background technique [0002] At present, there are mainly two varieties of colored cotton, brown cotton and green cotton (this application only involves green cotton). In the process of planting colored cotton, no toxic substances such as chemical fertilizers and pesticides are used. In the process of weaving, there is no need for bleaching, cooking, or dyeing It is the development direction of cotton varieties in the 21st century.

Problems solved by technology

The above two green cotton strains cultivated by the above methods still have deficiencies: one is that the fiber quality is still not ideal enough, it is still difficult to meet the requirements of the textile industry, and the textile industry users still cannot be adopted on a large scale; the other is that the color is still not deep enough, so in The color fastness in the textile process is still unsatisfactory; the third is that the output still needs to be improved
