US 11,032,984 B2 · Genes and SNP markers associated with lint percentage trait in cotton, and use thereof

Abstract

The present invention discloses genes and SNP markers significantly associated with lint percentage trait in cotton, and use thereof. The genes significantly associated with the lint percentage trait in cotton are genes Gh_D05G1124, Gh_D05G0313, and GhWAKL3. In the present invention, a CottonSNP63K gene array is used for genotyping, and genome re-sequencing data are analyzed to identify SNP markers significantly associated with the lint percentage trait in cotton. Moreover, the present invention also discloses use of the genes and SNP markers, which are significantly associated with the lint percentage trait in cotton, in cotton germplasm identification, breeding, or genetic diversity analysis.

Dependent claims

A method for selecting a cotton plant, comprising steps of:

extracting a genome from cotton plant to be analyzed;
analyzing said genome for the presence of genes Gh_D05G1124 and Gh_D05G0313;
analyzing the tenth exon region of the gene Gh_D05G1124 at base 6498 from a start codon of the gene;
analyzing the first exon region of the gene Gh D05G0313 at base 176 from a start codon of the gene;
and
selecting the cotton plant if base 6498 of gene Gh_D05G1124 and base 176 of gene Gh_D05G0313 is a GG genotype.
