摘要
以141份玉米高代回交重组自交系群体(RIL)及受体亲本黄早四于2011年在黄冈市农业科学院试验基地、2011和2012年在武汉市华中农业大学校内试验基地进行田间试验,对穗长、穗粗、株高、穗位高、吐丝期、散粉期、雄穗分枝数等7个农艺性状进行QTL分析。结果表明:7个农艺性状共检测到18个主效QTL,单个QTL的贡献为9.79%~37.35%,其中4个QTL在多个环境下同时检测到,5个QTL与前人的报道结果一致。
Plant height,ear height,ear length,ear diameter,tassel branch number,date to silk and date to pollen shedding are important agronomical traits in maize.In this study, a population of 141 RIL lines was used to map quantitative trait locus (QTL) of seven agronomic traits under three di{ferent en- vironments.A total of 18 QTLs associated with the seven traits were detected.Individual locus explained 9.79% to 37.35 % of phenotypic variance.Four of them were detected under more than one environment, and 5 QTLs were the same as those reported previously. It will provide basis for improving these agro- nomic traits in maize.
