以国际小麦作图组织的重组自交系群体W7984×Opata85为材料，对2005年收获的亲本和114个株系种子进行粒长、粒宽和粒形（长宽比）等粒型相关性状的鉴定和分析，并利用QTL作图软件WinQTLCart 2．5、基于混合线性模型的区间作图和复合区间作图方法，对控制小麦粒型的QTL进行定位，共检测到1个与小麦粒长相关的QTL，2与个小麦粒宽相关的QTL和5个与小麦粒形相关的QTL，分别位于2A，2B，3A，4A，5B，7A，7D染色体上。其中位于2A染色体的QTL贡献最大，可以解释粒长变异的21％。

In this study, a population of 114 RIL lines from the cross of W7984 ×Opata85 was evaluated for grain length、grain width and grain shape (the ratio of length to width). With the QTL mapping software WinQTLCart2.5 and the method of mixed-model interval mapping and composite interval mapping, one putative QTL related to grain length, two putative QTLs related to grain width and five putative QTLs related to grain shape were detected in this population and respectively located on chromosome 2A、2B、3A、4A、5B、7A、7D. The largest and most consistent grain length locus was identified on the long arm of chromosome 2A, accounting for 21%phenotypic variation.
