| 摘 要： | 以籼稻品种9311为受体、粳稻品种日本晴为供体构建的95个染色体片段置换系为材料,在5℃低温条件下进行芽期耐冷性鉴定。结果表明,6个置换系低温处理后的成苗率与受体亲本9311有一定差异,其耐冷性略强于9311。利用代换作图法共鉴定出4个与芽期耐冷性相关的QTL,分别位于水稻第5和第7染色体上。其中qCTB-5-1、qCTB-5-2和qCTB-5-3分别被定位在第5染色体RM267与RM1237、RM2422与RM6054及RM3321与RM1054之间遗传距离分别为21.3cM、27.4cM和12.7cM的置换片段上;qCTB-7被定位在第7染色体RM11-RM2752区间遗传距离为6.8cM的置换片段上。

| Abstract: | The cold tolerance at the bud bursting stage (CTB) were evaluated at 5℃ by using a set of 95 chromosome segment substitution lines (CSSLs) derived from indica rice 9311 and japonica rice Nipponbare. The results showed that six CSSLs had slightly stronger CTB than 9311. Total four quantitative trait loci (QTLs) for CTB were preliminary mapped on chromosomes 5 and 7 by substitution mapping. qCTB 5 1, qCTB 5 2 and qCTB 5 3 were mapped in the region of RM267-RM1237,RM2422-RM6054 and RM3321-RM1054, which were 21.3 cM, 27.4 cM and 12.7 cM in genetic distance on rice chromosome 5, respectively. qCTB 7 was mapped in the region of RM11-RM2752, which was 6.8 cM in genetic distance on rice chromosome 7. |
