| 摘 要： | 研究典型籼稻品种‘七山占’和典型粳稻品种‘秋光’杂交衍生的重组自交系群体及其双亲的花时性状,并用该群体的分子连锁图谱进行QTL分析,共检测到6个与水稻花时性状相关的QTL,包括1个始花时QTL、3个盛花时QTL和2个终花时QTL,分别位于第1、2、7、8、10和12染色体,单个QTL的贡献率在7.08%～26.95%之间。有4个增效等位基因来源于粳型亲本‘秋光’,2个来源于籼型亲本‘七山占’。

| Abstract: | QTLs for flowering time were identified in the population derived from a cross between typical japonica rice 'Akihilari' and indica rice 'Qishanzhan'.Totally,6 QTLs for the flowering time of rice were identified and mapped on chromosome 1,2,7,8,10,and 12,respectively.One putative QTL for flowering-begin-time was located on chromosomes 12.Three putative QTLs for vigorous-flowering-time were located on chromosomes 1,8 and 10.Two QTLs for flowering-end-time were located on chromosomes 2 and 7.The contribution ... |
