| 摘 要： | 本研究以98个Nipponbare／Kasalath／／Nipponbare回交重组自交家系（backcross-inbred lines，BILs）组成的群体为材料，进行水稻芽期耐冷性数量性状基因座的检测和遗传效应分析。25℃正常条件下水稻发芽7d，芽长5～10cm，5℃低温处理10d，之后升温至25℃，缓苗10d，调查活苗率，并以活苗率作为芽期耐冷性的表型值，分析亲本和98个BILs的芽期耐冷性表现。采用Windows QTL Cartographer 1．13a软件的复合区间作图法，共检测到4个苗期耐冷性数量性状基因座（quantative trait locus，QTL），分别位于第3、第7和第12染色体上，命名为qSCT-3-1、qSCT-3～2、qSCT-7和qSCT-12。4个QTL的加性效应分别为11．16、11．14、-8.8和-14．59，可解释表型变异的12．11％，12．66％，6．82％和15．86％。

| Abstract: | Low temperature induced retardation of seedling growth is a common problem in temperate rice growing areas. To gather more information regarding cold-tolerance in rice (Oryza sativa L.), we identified gene loci controlling cold tolerance at early seedling stage. We analyzed the quantitative trait loci (QTL) using 98 backcross-inbred lines (BIL) derived from the backcross between Nipponbare (strongly cold-tolerant rice, as recurrent parent) and Kasalath (cold susceptible rice). A total of 4 QTLs were detecte... |
