Molecular marker related to wool yield of long-haired rabbit and use thereof

Abstract

The present disclosure relates to the technical field of molecular marker breeding of rabbits, in particular to a molecular marker related to a wool yield of a long-haired rabbit and use thereof in breeding. The molecular marker includes a mutant of a keratin 26 gene (KRT26 gene), where the KRT26 gene is as shown in SEQ ID NO: 1, the mutant of the KRT26 gene is formed by mutation of a base G at position 41844263 of a KRT26 gene locus to a base A. In the present disclosure, the wool yield trait of the long-haired rabbit and the KRT26 gene are subjected to association study and population verification, and it is found that an individual long-haired rabbit with an allele G has a higher wool yield, with an additive gene effect of 15.59 g; the base substitution can control an overall genetic variation of the wool yield by 1.51%.
