Embodiment 1

[0061] Embodiment 1, the application of molecular markers of cotton clothing content in the detection of cotton clothing content

[0062] 1. Molecular markers of cotton clothing content related to cotton clothing content

[0063] The present invention has discovered a SNP locus related to cotton clothing content, which is recorded as a cotton clothing molecular marker. The molecular marker is changed to T or A in the cotton genome, and corresponds to the sequence table in the two chromosomes of low cotton clothing content The 310th nucleotide in sequence 1 is T, and the genotype of this cotton is recorded as TT genotype; this molecular marker corresponds to the 310th of sequence 1 in the sequence table in the two chromosomes of high-yielding cotton The nucleotides at the position are all A, and the genotype of the cotton is recorded as the AA genotype; one chromosome corresponds to the 310th nucleotide of sequence 1 in the sequence listing as T, and the other chromosome corres...

Abstract

The invention discloses a molecular marker of cotton clothing and its application. The present invention discloses a1) or a2): a1) the nucleotide corresponding to the 310th position of sequence 1 in the sequence listing in the cotton genome, and the molecular marker of cotton clothing is T or A; a2) contains the cotton described in a1) Molecularly labeled DNA fragments. The cotton clothing molecular marker and its primers provided by the present invention can quickly identify cotton strains with high clothing content. The assisted cotton breeding has played a decisive role in promoting the breeding process.

Description

technical field [0001] The invention relates to the molecular marker of cotton clothing and its application in the field of biotechnology. Background technique [0002] Cotton (Gossypium) is an important economic crop and oil crop in the world. Cotton fiber is an excellent natural spinnable fiber and an important raw material for the textile industry. The main goal of cotton breeding around the world is still to increase the yield of cotton fiber. Cloth content refers to the weight ratio of the fiber obtained after ginning to the whole boll seed cotton. It is one of the important production factors of cotton. Increasing the clothing content has a great effect on increasing the fiber production of cotton varieties. The results of the study showed that the heritability of clothing was high. In the past 40 years, the improvement of fiber yield of domestic and foreign commercial cotton varieties is closely related to the improvement of cloth content. Many studies at home and ...
