摘要： 以籼稻3037、Palghar和粳稻029、02428及其正反交F1为材料，探讨水稻籼粳亚种对光抑制和DCMU的耐性及其在杂种F1中的生理遗传特点。结果表明，亲本及正反交F1的PSⅡ活性对光抑制和除草剂的耐性基本上是一致的。粳稻大于籼稻，籼粳杂种F1分别与其母本相似。在育种上选用耐光抑制和DCMU（I50较高）的品种作母本是水稻生理育种中选亲配组的重要着眼点之一。

Abstract: To elucidate the tolerance of photoinhibition and herbicide DCMU in indica, japonica and physiological genetic in reciprocal hybrids F1,Three reciprocal crosses involving indica varieties 3037, Palghar and japonica varieties 02428, 029 were used for this study. Results showed that tolerance of photoinhibition was paralleled with DCMU affinity of PSⅡ(Ⅰ50), japonica was more than indica, indicating japonica was tolerant to photoinhibition and DCMU. Hybrids F1 were based towards(or similar) their materal parents. Selecting variety with tolerating photoinhibition and DCMU (higher Ⅰ50)as material might be an important approach in rice breeding.
