QTL Mapping of Heading Date and Yield-related Traits in Rice Using a Recombination Inbred Lines (RILs)Population Derived from BG1/XLJ
摘要
Abstract
Heading date and yield-related traits including plant height (PH),number of tillers per plant (NTP),panicle length (PL),number of filled grains per panicle (NFGP),grain number per panicle (GNPP)and seed setting rate (SR)are important agronomic traits in rice.Detection of new QTL associated with heading date and yield-related traits have great significance in new genes identification and utilization of rice.We used a recombination inbred lines (RILs) population derived from BG1/XLJ to detect QTL associated with heading date and yield-related traits in two environments,effects of epistatic and interaction with environments were also analyzed.A total of 32 QTL associated with heading date and yield traits were detected on chromosomes 2,3,4,5 ,6,7 and 8.Furthermore,five pairs of QTL intervals had significant two-factor epistatic effects,and 5 QTL had significant interaction with environments. Many yield related QTL detected were identified near the intervals where yield-related QTL were detected in previous researches.Among them, the QTL with large effects commonly clustered.Low epistatic and interaction with environments effects for yield related QTL,indicated small interactive effects between genes,genes and environments.关键词
