摘要:
结实率是评价水稻品种应用价值的重要农艺性状之一,是产量重要的构成因素,易受到高温、低温、干旱等环境因素的影响,对结实率QTL进行定位并研究其遗传效益在水稻育种中至关重要,为进一步精细定位及克隆相应QTL和开展水稻结实率分子育种奠定基础。以籼稻品种扬稻6号为受体、粳稻品种日本晴为供体构建的一套染色体片段代换系为材料,利用多元回归分析方法,结合Bin图谱,对代换系上的结实率QTL进行鉴定,结果表明,在水培条件下共定位14个控制水稻结实率性状的QTL,分别位于3~11染色体上,其中,2010年定位2个,2011年定位5个,2012年定位7个;贡献率大于20%的QTL共有9个,分别是qSSR5.1、qSSR7.1、qSSR9.1、qSSR11.1、qSSR3.2、qSSR3.3、qSSR4.1、qSSR8.2和qSSR9.2WTBZ][STBZ],其中,贡献率最大的QTL为qSSR5.1,贡献率为49.76%,被定位在第5染色体上731 482 bp区间内。
