摘要
HyBrid rice's history and its development up to date are described in the paper. Compared with the conventional rice. hybrid rice can increase grain yield by about 20%. Hybrid rice breeding in China has been advancing along the three-line method, to two-line method, to super high-yielding rive application strategically and its success in higher degree will be seen by the utilization of distant heterosis cooperated with bioteehnology.
