Abstract

The invention discloses a gossypium anomalum chromosome segment capable of increasing the strength of cotton fiber and molecular markers thereof. The gossypium anomalum chromosome segment capable of increasing the strength of cotton fiber comes from gossypium anomalum and is a segment on the chromosome 1 of the gossypium anomalum and from the SSR (simple sequence repeats) molecular marker of NAU3615 to the SSR molecular marker of JAAS1148; the nucleotide sequence of the SSR molecular marker of NAU3615 is shown as SEQ ID No. 1, and that of the SSR molecular marker of JAAS1148 is shown as SEQ IDNo. 2. The gossypium anomalum chromosome segment capable of increasing the strength of cotton fiber achieves high application value in high-fiber-strength cotton breeding; meanwhile, the SSR molecular markers can applied as a molecular foundation to produced high-fiber-strength cotton varieties.

Description

technical field

[0001] The invention relates to the field of cotton breeding, in particular to abnormal cotton chromosome fragments capable of improving cotton fiber strength and molecular markers thereof. Background technique

[0002] Cotton fiber is an excellent natural fiber and an important raw material for the textile industry. Due to the continuous acceleration of the processing speed of the textile industry and the improvement of people's living standards, higher and higher requirements are placed on the quality of cotton fibers. Cotton fiber quality consists of many physical properties, mainly: fiber strength, fiber fineness, fiber length and uniformity. Fiber strength refers to the strength of cotton fiber against tensile fracture. When other indicators are basically the same, fiber strength has a positive correlation with yarn and cloth quality. In the case of relatively high speed of modern spinning equipment, the strength of cotton fiber is high, which plays a ...
