| 摘 要： | 为定位控制小麦产量相关性状的QTL位点，获得与重要位点连锁的分子标记和染色体区段，以分别含有229和485个家系的关联重组自交系(RIL)群体WY和WJ为材料，在4个环境中，用完备区间作图法(ICIM)对产量相关性状进行了QTL定位分析。结果表明，产量相关性状QTL分布在小麦21条染色体上。在WY群体中检测到每穗小穗数、主茎穗粒数、单株穗数、千粒重和单株产量的QTL分别有9、9、4、7和5个，其中16个(55.2%)解释大于10%的表型变异；在WJ群体中检测到这5个性状的QTL分别有20、16、11、14和9个，其中只有3个(6.7%)在单个环境中解释超过10%的表型变异。在WY群体中有5个QTL在2个环境中被重复检测到；在WJ群体中，有11个QTL在2个或2个以上环境中被重复检测到。在2个群体中均检测到产量相关性状的QTL在染色体上形成了含有一因多效或紧密连锁QTL的染色体区段，并在2个群体检测到可能相同的9对QTL和2个染色体区段。

| Abstract: | Using inclusive composite interval mapping(ICIM) method,we detected QTLs responsible for spikelet number per spike(SN),grain number per spike(GN),spike number per plant(PN),1000-grain weight(GW),and grain yield per plant(GY) in associated RIL populations WY(229 lines) and WJ(485 lines),which were planted in four growing environments.Numerous QTLs for the five yield-related traits were located on 21 chromosomes of wheat.In the WY population,nine,nine,four,seven,and five QTLs were detected for SN,GN,PN,GW,and... |
