A HYBRID RICE SEED PRODUCING METHOD

摘要

A hybrid rice seed producing method includes steps as follows: (1) breeding small grain sterile line and corresponding hybrid rice with properties of Zhong Hua 11 small grain mutant (CGMCC No.2741); (2) hybridizing the small grain sterile line with large grain or normal grain maintaining line hybrid rice for seed producing; (3) carrying out mechanized seed producing by utilizing the small grain sterile line hybrid rice to perform mixing sowing and mixing harvesting; (4) screening and separating of seeds after mechanical harvest. By applying said method simplifies the seed producing procedures and reduces the cost of seed producing.
