SNP-based QTL mapping for panicle traits in the japonica sup

发布时间：2021-04-18 23:01

　　Panicle traits directly associated with yield are a target of selection in rice breeding.Although abundant QTL for panicle traits have been identified, there is little information about the genetic basis of panicle traits in japonica super rice（JSR） cultivars. In this study,we identified QTL for panicle traits in three environments using a population of recombinant inbred lines（RILs） derived from the JSR cultivar Liaoxing 1. A total of 197 RILs were genotyped with 285 polymorphic SNP markers. Ph...
