Objective] The main biological effects of leaf rol ing of rice was studied to provide the theoretical basis for the application of RL （t） in the breeding of the rice. [Method] A rice mutant with adaxial y-rol ed leaf was found in breeding, temporarily named as RL （t）. The differences were researched in which light interception struc-ture, light transmission photosynthetic efficiency and cel ular structure comparison between RL （t） and its sister lines that had flat leaf. [Result] Both leaf rol ing index and leaf erecting index of RL （t） were higher than those in 0731-3-1-1B. However, its basic leaf angle and leaf drooping angle were significantly lower than those in 0731-3-1-1B in upper three leaves, which caused a great raise in the photosynthetic rate on account of the light transmittance of RL （t）’s population were significantly higher than that of 0731-3-1-1B especial y the upper and middle part. The stomata conductance and the intercel ular CO2 concentration of the upper three leaves and transpiration rate of the flag and the second leaf were also significantly higher than that of 0731-3-1-1B. The bul iform cel s became smal er, leading to the rol ing up of leaves. [Conclusion] The study provided a theoretical basis for the principle of high-yielding breeding with the application of the adaxial y-rol ed leaf mutant in rice.
