| 摘 要： | Grain yield in cereal crops was an eternal theme. The number of panicles per plant (PN), filled spikelets per panicle (FSP), and 1000-gram weight (TGW) were the three important yield components. Some QTLs for rice yield had been mapped, but conditional QTLs for grain yield had not been analyzed. Phenotypic values of yield traits, which had no influence on the given components, were used for QTLs conditional analysis. This study was to uncover conditional QTLs for rice yield in a RIL population, and to search for evidences on the genetic basis of yield QTLs.
