Mapping of Major QTLqSCT-11 for Early Seedling Cold Tolerance in Rice

GONG Xun~(1,2) CAI Hai-yan~2 LIU Shao-jiao~2 ZHANG Zhi-hong~2 (1 Department of Environment and Life Sciences,Bijie University,Bijie,Guizhou 551700,China;2 College of Life Sciences,Wuhan University,Wuhan,Hubei 430072,China)  
In order to identify the major QTLqSCT-11 in specific genome region of chr 11,a high-density molecular litage map of chr 11 in specific genome region was constructed.A recombinant inbred line population derived from an japonica-indica cross(Lemont/Teqing)were assessed for cold tolerance at early seedling stage at 10℃.The date combined with the high-density molecular linkage map of chr 11 were used to map the major QTL conferring cold tolerance by a computer program WinQTLCart based on composite interval mapping.According to the mapping results,the major QTLqSCT-11 was identified between adjacent markers ID7924-3 and RM202,which was also adjacent to the centromere region of chr 11.
