| 摘 要： | 用水稻测序品种培矮64s和Nipponbare为亲本构建的含137个SSRs标记的连锁遗传图谱和（培矮64s/Nipponbare）F2群体的180个单株，对水稻的单株有效穗数、穗粒数、穗实粒数、结实率、穗着粒密度、千粒重等6个产量构成性状进行了QTL定位分析。共检测到6个性状的22个QTLs，分布在第1、2、4、5、6、9、10、11、12等9条染色体的14个区域,表型贡献率5.0%-19.3%;相关性较强的性状之间具有较多共同或紧密连锁的QTLs;集中分布的QTLs之间既有同向连锁.对不同水稻群体定位的同源QTL进行了比较,对QTL在染色体上的集中分布,以及用QTL定位结果和生物信息学方法相结合预测基因的英勇等进行了探讨。

| Abstract: | Recently QTL (quantitative trait loci) mapping has mostly adopted such markers as RFLP marker, which is costly and difficult to operate. Besides, in such mapping the genome information of the mapping parents is not known, which makes it difficult to compare and share the outcomes achieved by different researchera. QTL mapping, using genetic linkage map constructed by sequenced rice cultivar, will facilitate the application of rice genome outcomes, and can provide a basis for the comparison of different rice QTL mapping and molecular marker assistant selection. It will prove to be a pathway to integrate QTL mapping and genome findings application. |
