ABSTRACT
Schizothorax prenanti (S. prenanti), an economic fish in China, has rich nutritional value and high economical value. In order to acquire some reliable molecular genetic markers for growth traits, correlation analysis between 31 SNP markers and growth traits in S. prenanti was analyzed using 164 samples with the same growth conditions. Principal component analysis showed that the body weight accounted for 94.50% of the variance, the eigenvalue was greater than 1, and the accumulative variance was more than 85%. So, the body weight was the first principal component of the growth traits for S. prenanti. Association analysis indicated that ug25066-1502 had significantly associated with total length and body weight; and ug22539-1605 and total length, body length, body height, and body weight were significantly associated. In conclusion, ug25066-1502 and ug22539-1605 were significantly associated with the growth traits, which could be used as important candidate molecular markers for selective breeding of S. prenanti.
