摘　　要：对杂交水稻异质四系三交种的应用价值作了探讨 ,初步的研究结果表明 :通过引进具有不同优良品种特性的二元保持系 ,在保持所选育杂种品种主要农艺性状整齐一致的前提下 ,可较大幅度地拓宽品种的遗传基础。从而为解决杂交水稻品种选育过程中的多抗、广适、高产、优质等综合育种目标的集成与实现 。In this paper, the application value of hybrid rice combination that was bred by three-way cross was discussed. The preliminary results showed that by the way of using the second male sterile maintainer with different good agronomic characters,e.g.resistance to insects and diseases, good stability at wide adaptability, good quality and high-yield,could be combined into same hybrid rice combination and the identity of main agronomic traits in the combination at the same time could be kept.
