摘要 为稻谷产量性状QTL定位研究提供新素材,以V20B和CPSLO17作为亲本,构建150份V20B/CPSLO17重组自交家系(RIL)。结合RIL群体的稻谷千粒重表型数据,运用MapQTL5软件的区间作图法进行稻谷千粒重QTL检测及其遗传效应分析。结果表明:有1个新的控制稻谷粒重QTL,命名为qTGW-3,其LOD值为4.14,对表型变异的解释率为11.9%,等位基因效应来源于亲本V20B。 To provided new experimental materials for QTL analysis of rice yield trait,the authors constructed a mapping population of 150lines(recombination inbred lines,RIL)derived from a cross between rice varieties V20 Band CPSLO17,and analyzed QTLs location and evaluated the genetic effects of two parents and 150 RILs for thousand-grain weight trait by using internal mapping method of MapQTL5 software and combining thousand-grain weight phenotype data of RILs.The result showed that a new QTL(qTGW-3)related to thousand-grain weight trait was detected.Individual QTLs(LOD=4.14)explained 11.9% of the observed phenotypic variance.And the QTLs alleles came from the parent V20 B.
