Abstract

The invention relates to the field of molecular biology of characters of fiber yield, in particular to a gene in significant correlation with the characters of the fiber yield, a SNP marker and application of theSNP marker. The gene in significant correlation with the characters of the fiber yield is a Gh_D05G1124 gene and / or a Gh_D05G0313 gene. 276 upland cotton materials are taken as raw materials and planted in multiple environments, a CottonSNP63k gene chip is adopted for genetic typing, and 10660 high-quality SNPs are obtained and used for analyzing of the genetic structureand GWAS. According to the result, 23 SNPs in significant correlation with the characters of the fiber yield are discovered to correspond to 15 QTLs. In addition, through Qrt-PCR analyzing, the Gh_D05G1124 gene andthe Gh_D05G0313 gene are taken as candidate genes for adjusting the characters of the fiber yield, the SNP marker in significant correlation with the fiber yield is obtained, and theoretical support is provided for research and application of the characters of the fiber yield.

Description

technical field

[0001] The invention relates to the field of molecular biology of cotton clothing properties, in particular, relates to genes significantly related to cotton clothing properties, SNP markers and applications thereof. Background technique

[0002] Cotton is the main source of natural textile fibers and an important economic crop in the world. Upland cotton (Gossypium hirsutum L.), an allotetraploid cotton species, accounts for about 95% of global cotton production. Increasing cotton yield has always been an important goal of cotton breeding work. Among them, lint yield is an important indicator to measure cotton yield, which is composed of boll number per plant, clothing percentage, and boll weight per plant. Numerous studies have found that there is a significant positive correlation between coat content and cotton yield, and coat content is also an important trait index for high-yield cotton breeding. However, the traditional breeding work only improves t...
