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.

通过叶片切片培养，在日本和世界水稻种质资源中检测到不同的绿色保持能力基因型差异。在花后高温条件下，维持能力与光合作用和生产力的维持有关。F2代叶色在持绿绿色与非持绿绿色或高产品种与持绿绿色突变体间的差异性分布。在岛根和冲绳的稻田条件下，观察到绿色叶保持和生产力的基因型差异。从我们的研究结果来看，花后持绿性状有望有助于在包括高温在内的各种环境条件下提高水稻产量。
