摘　　要：株高是大豆产量的一个影响因子,该性状的基因定位对于大豆育种具有重要的理论和应用价值。以绥农14×绥农20的F2代154个单株为材料,对各单株及亲本的株高性状进行调查和SSR分析。构建一张包含65个SSR标记的遗传图谱,用QTL软件分析,在F2代共检测出2个与株高相关的QTL位点,命名为PIht-1和PIht-2位点,均分布在G连锁群。The plant height is a impact factor of soybean yield, so mapping the plant height trait loci in the genetic map has important theoretical and applied values. One hundred and fifty-four individuals of F2 population derived from a cross between Suinong 14 and Suinong 20 were used in this experiment. Both plant height and SSR data were investigated for mapping plant height QTLs. A genetic linkage map was constructed with 65 SSR loci screened with two parents and analyzed among 154 individuals of the population. Two plant height QTLs,named as PIht- 1 ,PIht-2 in the G linkage group were identified.
