摘　　要：本研究共配制了185个杂交组合,包括单交组合133个、三交组合17个、四交组合35个,在主要分离世代对选择效果进行了分析,结果表明:F2代和F4代的三交组合的优良组合入选率明显高于单交组合和四交组合,四交组合优良单株入选率高于单交组合和三交组合。This study was prepared 185 combinations,including 133 single-cross hybrid combinations,17 triallel mating combinations,35 four-cross hybrid combinations.The paper discussedt he selection effect of the main segregation,the results showedt hat：the triallel mating combination selection rate of generation F2 and F4 was significantly higher than that of single-cross andf our-cross combinations;and the selection rate of per plant off our-cross combination was higher than that of single-cross andt riallel mating combinations.
