Breeding method of transgenic high-quality upland cotton new variety

Abstract

The invention discloses a breeding method of a transgenic high-quality upland cotton new variety. The breeding method comprises the steps that a parent Hunan 176 line is subjected to breeding, a parent Hunan 267 is subjected to breeding, hybridizing and composite hybridizing are carried out by taking the Hunan 176 line and the Hunan 267 as parents, and the transgenic high-quality conventional upland cotton new variety is obtained in offspring of the parents. The plant type of the variety is in a tower shape, the seedling stage growth vigor, the boll opening stage growth vigor and uniformity are good, stalk cilia are dense, anthers are white, boll opening is smooth, agronomic characters are stable, and the yielding ability is good. The fiber quality is excellent.

Description

technical field [0001] The invention relates to a method for breeding new varieties of cotton, in particular to a method for breeding new varieties of transgenic high-quality upland cotton, and belongs to the technical field of cotton breeding. Background technique [0002] Domestic high-quality cotton has always been favored by the market, and the price remains high. The reason is that high-quality cotton can achieve more efficient mechanical operation, higher-quality products, and more profit margins. Every year, almost all of my country's cotton import quotas are used for the import of high-quality cotton. According to statistics, the cumulative import volume of Australian cotton in my country reached 3 million tons in 2011-2015 alone, accounting for about 20% of the total global imports. Cotton production has been pinched by American cotton and Australian cotton for a long time. The situation of low production capacity, insufficient supply capacity and weak competitivenes...

Every year, almost all of my country's cotton import quotas are used for the import of high-quality cotton. According to statistics, the cumulative import volume of Australian cotton in my country reached 3 million tons in 2011-2015 alone, accounting for about 20% of the total global imports. Cotton production has been pinched by American cotton and Australian cotton for a long time. The situation of low production capacity, insufficient supply capacity and weak competitiveness is still difficult to improve. The high-quality cotton that meets the standards of American cotton and Australian cotton is less than 200,000 tons
