Abstract: This study reviewed the current research status of indica-japonica rice breeding practices, and analyzed the difficulties and solutions in the utilization of heterosis in subspecies. Meanwhile the authors summarized the principal issues to make use of indica-japonica subspecies heterosis completely. As well as combined the agricultural production and breeding practice, the utilization of heterosis between indica and japonica rice is prospected.
