In this study,197 mini-core germplasms of cultivated rice were screened using S5n function markers,1 1 genotypes with wide compatibility S5n gene were confirmed which were Huhui 628,Benbanggu,Haobuka,Xiaohonggu,Fanhaopi,Feienuo 2,Teqingxuanhui,Baoxie-7B, Haomake,Qingke and Laozaogu,and their compatibility were verified by crossing them with typical indica 9311 and japonica Nipponbare.The result indicated that the fertility of all the F1 was above 7 5%,presenting the wide compatibility.These wide compatibility materials provided more available resources for utilizing subspecies heterosis and breeding new varieties.
