Problems solved by technology

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

Embodiment 1

[0015] The breeding method of the transgenic high-quality upland cotton new variety of the present invention is specifically realized according to the following steps:

[0016] Step 1. Breeding of the parent Xiang 176:

[0017] In the summer of 2008 in Changde, Hunan Province, the medium-to-long-staple love-word cotton line (poor yield, good quality, low lint by about 38%) and the disease-resistant variety Xiangmian No. 18 (good yield, poor fiber quality, low lint) and The highest score is about 43%) as the parental crosses with each other to obtain the reciprocal F1 combination seeds;

[0018] The reciprocal cross combination F was planted in Sanya, Hainan in the winter of 2008 1 And carry out compound hybridization (quantitative traits of cotton are affected by cytoplasmic inheritance, and its progeny traits are partial to the female parent. Reciprocal cross combination is used for compound hybridization to reduce the influence of cytoplasmic inheritance on offspring and in...

Abstract

The invention discloses a breeding method for a new variety of transgenic high-quality upland cotton. A new transgenic high-quality conventional upland cotton variety was obtained in its offspring. The plant type of this variety is tower type, with good growth vigor in seedling stage, good growth vigor in flocculation stage, good uniformity, dense stalk cilia, white anthers, smooth flocculation, stable agronomic characters and good yield. 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 quota is used for the import of high-quality cotton. According to statistics, the cumulative import volume of Australian cotton in my country from 2011 to 2015 alone reached 3 million tons, accounting for about 20% of the total global imports. The production of cotton has been hit by the US cotton and Australian cotton for a long time. The situation of low production capacity, insufficient supply capacity and weak competitiv...
