摘　　要：对11个辽宁省新育成的杂交粳稻品系与常规粳稻产量性状进行了比较,结果表明:杂交粳稻新组合的丰产性比常规粳稻好,其主要增产因子是穴穗重、株高、穴茎秆重、穗粒数;产量性状较好的杂交粳稻品系有5215、20159、946、辽优3006、辽优5273、辽优5206。Eleven hybrid japonicas and conventional japonicas were compared in Liaoning. The results showed that the productivity of the hybrid japonicas was better than that of conventional japonicas. Main yield-increasing factors were weight per hill, plant height, plant stem weight per hill and grain number per panicle. Hybrid japonicas which had better yield characteristics were 5215, 2015,9946,Liaoyou 3006,Liaoyou 5273,Liaoyou 5206.
