Vernalization gene and photoperiod gene of wheat are major factors that influence wheat heading. This thesis tested and identified four sites of Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 using 11 pairs of STS markers for 260 wheat varieties from varied wheat-growing areas. Based on growth conditions of wheat in Huaibei of Anhui province, we analyzed the influence of dominant and recessive conditions of 4 sites of vernalization gene on growth habit of wheat and the distribution of various dominant alleles in...
