摘要:
水稻的穗长和有效穗数与产量有着密切的关系。本试验以籼稻品系中的V20B为母本,爪哇稻品系中的CPSLO17为父本杂交,经单粒传法构建重组自交系(RIL)为作图群体,对水稻穗长和有效穗数2个穗部性状进行QTL定位及分析。利用SLAF标签构建的高密度遗传图谱,结合定位软件MapQTL5进行区间作图,阈值设为3.9,在3条染色体上共检测到7个QTL,其中5个控制穗长QTL(qPL1-1、qPL1-2、qPL6-1、qPL6-2、qPL6-3)分别位于第1、第6号染色体上,QTL的贡献率分别为6.41%、22.22%、6.15%、12.24%、13.01%,增效位点主要来自于CPSLO17,且qPL1-1为一个新的QTL;2个控制有效穗数QTLs(qPN1、qPN4)分别位于第1、第4号染色体上,QTL的贡献率分别为13.15%、8.18%,且增效位点来自于亲本V20B。这些位点的标记为进一步克隆穗长和有效穗数QTL及分子标记辅助选择奠定理论基础。
