The germination vigor of wheat seeds is an important indicator of wheat quality, which is directly related to the seed germination and spike germination of wheat. To identify the genetic loci that regulate wheat seed vigor-related traits and explore candidate genes, a natural population consisting of 163 wheat varieties (lines) from the Huang-Huai wheat region was used as experimental materials to investigate three seed vigor-related traits of germination rate, germination potential, and germination index. A genome-wide association study was conducted using a 90K SNP array. The results showed that the seed germination rate, germination potential and germination index of the tested materials showed a rich variation, and the coefficient of variation ranged from 11.81% to 25.58. A total of 196 significant SNPs were identified that were associated with the three seed vigor-related traits using the 90K SNP array. Among them, 67 SNPs can be detected simultaneously for all the three traits. Through gene expression pattern and haplotype analyses, it was speculated that TraesCS4B02G359600 and TraesCS4A02G494700 may be important genes regulating wheat seed vigor.
