Abstract

The application discloses a SNP marker related to wheat kernel alpha-tocopherol content and application thereof. The application provides application of a substance for detecting a SNP site Ta-6A-SNP haplotype in a wheat genome in any one of the following: A1) identifying or assisting in identifying wheat kernel alpha-tocopherol content; A2) screening or assisting in screening wheat with high alpha-tocopherol content in kernels; A3) breeding wheat with high alpha-tocopherol content in kernels; A4) wheat genetic breeding. The application finds a SNP site Ta-6A-SNP on a 6A chromosome of wheat, and develops a molecular marker according to the SNP, which is a KASP marker, has good repeatability, low cost, is beneficial to screening wheat varieties with high alpha-tocopherol content, and has important significance for cultivating new wheat varieties with high alpha-tocopherol content.
