摘要: 用在小麦品种农大015和复壮30间具有多态性的10对SSR引物,对两品种的杂交F2群体进行SSR分析,并通过单一标记分析法对控制小麦株高、产量性状的QTLs进行了标记与性状之间的相关性分析,发现了4个与株高和产量性状QTLS相关的SSR标记.
英文摘要: A 124 F2:3 population developed from the cross between wheat varieties Nong-da015 and Fuzhuang30 was made for molecular maker analysis for plant height and yield components in winter wheat. Ten polymorphic SSR primers were used to genotyp p2 population. Four of them were found to be significantly associated with plant height or grain yield. They were gwm339 and gwm294 on chromosome 2A, g wm471 on 7A, and gwm582 on 1B.
