Abstract

The cold tolerance at the bud bursting stage (CTB) was evaluated at 5°C by using a set of 95 chromosome segment substitution lines (CSSLs) derived from an indica rice 9311 and a japonica rice Nipponbare with a genetic background of 9311. The result showed that six CSSLs had slightly stronger effect on 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 a 6.8-cM region of RM11-RM2752 on rice chromosome 7.

利用染色体片段代换系检测水稻发芽期耐冷性QTL

以遗传背景为9311的籼稻9311和粳稻Nipponbare的95个染色体片段代换系(CSSLs)为材料，在5℃条件下对萌发期(CTB)的耐寒性进行了评价。结果表明，6种cssl对CTB的影响略强于9311。通过代入定位，在5号和7号染色体上初步定位到4个CTB数量性状位点。qCTB-5-1、qCTB-5-2和qCTB-5-3分别定位于水稻第5染色体上遗传距离分别为21.3 cM、27.4 cM和12.7 cM的rm267 ~ rm1237、rm2422 ~ rm6054和rm3321 ~ rm1054区域。qCTB-7定位于水稻7号染色体RM11-RM2752的6.8 cm区域。
