Abstract:

以晋大52为母本、晋大57为父本及其176个RIL群体后代为材料,应用WinQTLCartV2.0软件采用复合区间作图法对所选取对象(LOD>2.5)的生育期、开花日数、单株质量、单株粒重、单株粒数、单株荚数、百粒重、株高、茎粗、主茎节数、分枝数、结荚高度等12个农艺性状进行QTL定位分析。结果表明:效应最大的QTL可解释的遗传变异分别为md221.32%、fd248.11%、wp17.01%、swpp130.67%、nppp241.32%、spp18.56%、sw441.46%、ph152.51%、st135.14%、snn231.60%、bn225.43%、hp116.31%。检测到的30个QTL分布于山西农业大学大豆研究实验室建立的5个连锁群上,大多数性状聚集在c2(Dla)、c5(C2)、c7(M)等连锁群上,部分QTL在连锁群上的位置相同,即为同一位点,这类位点共有5个,除去重复计算部分,实际位点数为23个。
