Abstract:In order to understand the allelic variation and distribution of preharvest sprouting (PHS) genes in whet verieties of different regions, we genotyped 446 wheat cultivars from 7 wheat regions by the functional markers Vp1B3 and Dorm1 related to PHS resistance in China. The results indicated that: (1) Vp1 had three allelic variations detected by the marker Vp1B3: Vp1Bc (related to resistant PHS), Vp1Bb (related to resistant PHS) and Vp1Ba (related to susceptible PHS), and their frequencies were 62.8%, 4.3% and 32.9%, respectively. (2) DormB1 had two kinds of specific bands detected by the marker Dorm1:468 bp (genotype of DormB1a, correlated with susceptible PHS) and 606 bp (genotype of DormB1b, correlated with resistant PHS) accounted for 98.6% and 1.4%, respectively. (3) The detection by marker Dorm1 showed wheat germplasms with the genotype of DormB were distributed in Huanghuai winter wheat region (HHWWR) and Yangtze River middlelower reaches winter wheat region (YMWWR), with the ratios of 5.1% and 1.9%, respectively. The results of Vp1B3 indicated that wheat germplasms with (Vp1Bc+Vp1Bb) genotype (combination) were mostly distributed in YMWWR and Southwestern winter wheat region (SWWWR ) with the ratios of 75.0% and 74.1%, respectively. (4) Through the comprehensive identification of Vp1B3 and Dorm1 markers, 6 accessions of Vp1 and DormB1 loci related to resistant PHS were screened out, which were ‘Shanmai 611’, ‘Zhengnong 19’, ‘Yu 49198’, ‘Xinyang 0913’, ‘XianyangDasui’ and ‘Xuzhou 8066’, respectively. These accessions could be used as reference parents for PHS resistance breeding.
