By leaf-section incubation, diverse genotypic differences in green color maintenance capacity were detected in Japanese and World Rice Collection. Under high temperature conditions in the post-anthesis period, the maintenance capacity related with maintenances in photosynthesis and productivity. Leaf color by the incubation in F2 between stay-green and non-stay green or high yielding cultivar and stay-green mutant diversely distributed. Under paddy field conditions in Shimane and Okinawa, genotypic differences in green leaf maintenance and productivity were observed. From our results, stay-green trait in the post anthesis period is expected to contribute to an improvement of rice production under diverse environmental conditions including high temperature.

通过叶片孵育，在日本和世界稻米收集中检测到绿色维持能力的各种基因型差异。在大麻后期的高温条件下，维护能力与光合作用和生产率的维护相关。通过在绿色和非停机绿色或高产品种和绿色突变体分布的叶子中孵育叶子颜色。在Shimane和冲绳的稻田条件下，观察到绿叶维持和生产力的基因型差异。从我们的结果来看，预期在包括高温在内的各种环境条件下的水稻产量会改善水稻产量。
