The present application provides a SNP
molecular marker related to
naked barley grain beta-
glucan content, which is closely linked to
naked barley grain beta-
glucan content, and the SNP
molecular marker is a
nucleotide sequence shown in SEQ ID NO:1, and a G / A base
mutation exists at the 132th base from the 5' end of the
nucleotide sequence shown in SEQ ID NO:1. The application also provides the application of the above-mentioned SNP
molecular marker, a primer pair for detecting the SNP molecular marker, and the application of the primer pair. The SNP molecular marker related to
naked barley grain beta-
glucan content of the present application can detect naked
barley grain beta-glucan content at the
seedling stage, so that the screening of naked barley with high grain beta-glucan content can be realized at the
seedling stage, thereby accelerating the breeding process of naked barley with high grain beta-glucan content, and being suitable for large-scale popularization and application.
