The mutant line M8008 with large plant height and grain weight was obtained from the wheat cultivar Yannong 15 induced by ethylmethane sulphonate(EMS).The F2 and F2∶3 generations from the cross of M8008 × Yannong 15 were used for polymorphism detection with SSR markers.The preliminary analysis showed that Xwmc76 and Xwmc426 on chromosome 7B linked with plant height,and there were other four SSR markers on this chromosome showing polymorphism in the preferred small group(PSG).The six markers were used for sc...
