| 摘 要： | 以一套用籼稻品种9311为受体、粳稻品种日本晴为供体构建的128个染色体片段代换系为材料，按随机区组实验设计种植，于成熟后考查代换系粒长、粒宽性状，利用多元回归分析方法，结合Bin图谱，鉴定出6个与粒长相关的QTL、2个与粒宽相关的QTL。其中，qGL3.1被定位在水稻第3染色体的5 792 954 bp区间内；qGL3.2被定位在第3染色体的917 878 bp区间内；qGL8.1被定位在第8染色体的889 543 bp区间内；qGL8.2被定位在第8染色体的208 614 bp区间内；qGL9.1被定位在第9染色体的1 149 685 bp区间内；qGL11.1被定位在第11染色体的3 184 760 bp区间内；qGW1.1被定位在第1染色体的200 070 bp区间内；qGW5.1被定位在第5染色体的704 905 bp区间内。上述QTL的准确定位，为进一步精细定位及克隆相应QTL和开展水稻粒型分子育种奠定了基础。 |

| Abstract: | One hundred and twenty-eight chromosome segment substitution lines derived from 9311 as recipient and Nipponbare as donor,were used for mapping QTLs for grain shape by combining the sequencing-based Bin-map with a multiple linear regression analysis.Six and two QTLs were identified for grian length(GL) and grian width(GW),respectively.qGL3.1 was mapped in a region of 5 792 954 bp on chromosome 3,qGL3.2 in a region of 917 878 bp on chromosome 3;qGL8.1 in a region of 889 543 bp on chromosome 8;qGL8.2 in a reg... |
