Research Abstract

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.
