In order to identify preharvest sprouting (PHS) tolerance of breeding materials, in this study, two STS markers Vp1A3 and Vp1B3 associated with PHS tolerance, were used to evaluate the PHS tolerance in 107 Chinese historical wheat cultivars. Three genotypes, Zhengzhou 742,Shannong 17 and Neixiang 5, were resistant to PHS haplotype of Vp 1Agm.Ten genotypes, Yuejin 5,Taishan 1,Jinan 12,Jingyang 60, Fuzhuang 30, Fengkang 15, Jinong 2, Beijing 8, Jinanai 6 and Jing 130, were resistant to PHS haplotype of Vp 1Bb. Forty eight genotypes were resistant to PHS haplotype of Vp 1Bc.The results showed that the average germination index of five genotypes, such as Anxuan 2, Yannong 15, Zhengzhou 683, Zhengzhou 742 and Kequn, was less than 10%, among 77 genotypes with data of average germination index. These results broaden the scope of parent selection and are useful in wheat improvement for PHS resistance. |
