AI Technical Summary
Existing methods for breeding Hu sheep rely on phenotypic indicators, which have long testing cycles, low early selection efficiency, and are easily affected by the environment. There is a lack of effective molecular marker-assisted methods for early screening of high-quality individuals.
By detecting the SNP site g.39045A>C of the CNGA3 gene, and using PCR amplification and direct sequencing technology, the correlation between different genotypes of this site and the growth traits of Hu sheep was analyzed. Molecular markers and kits for screening candidate individuals with superior body length were provided, and the superiority or inferiority of individuals was determined by combining genotype.
It enables early and efficient screening of body length traits in Hu sheep, improves breeding efficiency, and provides a molecular breeding tool that can be used for commercial purposes, guiding the early identification of high-quality breeding sheep.
