摘要: Molecular markers for vernalization genes Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 photoperiod gene Ppd-D1 were used to detect the presence of these among 755 cultivars from 23 countries. Days heading physiological maturity also recorded in Anyang, Henan Province, China provide information their utilization Chinese wheat breeding program. Frequencies Vrn-D1, vrn-A1+vrn-B1+vrn-D1 13.0%, 21.1%, 15.6%, 64.2%, respectively. Dominant allele was absent all tested materials. alleles mainly observed spring middle upper Yangtze Valley winter regions, Italy, India,
