| Abstract: | The new questions on seed-making of hybrid Japonica rice were analyzed such as characters of parents have flaws, there were few continuous base （large area）, labor shortage, technical innovation shortage, low yield, high cost, high risk and low efficiency. For these problems, it put forward the solution which were cultivating parents with fine outcrossing feature, applying seed production technique with entire mechanization, strengthen study on matching technique of seed-making of hybrid Japonica rice, increase effort on high-quality varieties and building standardization breeding base. |
