Abstract: In order to get wheat cultivars with resistance to pre-harvest sprouting(PHS) and provide theory evidence for anti-PHS breeding in Xinxiang region,a functional marker Vp1B3 was used to investigate 112 wheat cultivars breed by Xinxiang Academy of Agricultural Sciences.Germination percentages on ear of those cultivars were counted indoor at the same time.The results's indicated that the frequencies of cultivars with the genotype Vp-1Ba (susceptible to PHS), Vp-1Bb (resistant to PHS) and Vp-1Bc (resistant to PHS) were 60.71%,0.89% and 38.39%,respectively.The genotype Vp-1Ba was the major genotype in those wheat cultivars.The germination percentages of cultivars with genotype Vp-1Ba (24.42%) and genotype Vp-1Bc (16.55%) was remarkable different.The germination percentages among cultivars from the same parental cross varied greatly,but genotypes of Vp-1 were almost identical among cultivars from the same parental cross.Pre-harvest sprouting rate of cultivars with the same Vp-1 genotype also varied greatly,therefore the application of Vp1B3 marker should be combined with the test of germination on ear.

Key words: Wheat, Pre-harvest sprouting, Vp-1 gene, Vp1B3 marker
