Abstract: RFLP markers were used to study the relationship between indica-japonica differentia-tion and heterosis of growth period and plant height. The results of 58 varieties from America, Africa, China, Japan, Korea by 45 indica-japonica differentiating probes indicated that indica-japonica differentiation had no obvious relationship with heterosis of growth period, but correlated significantly with heterosis of plant height.

Key words: Rice, RFLP, Indica-japonica differentiation, Growth period, Plant height, Heterosis
