摘要： The invention relates to a method for simplifying hybrid rice seed production procedure and improving the working efficiency of seed production. The method comprises the following steps: (1) breeding small grain CMS or GMS line and corresponding hybrid rice having characteristics of rice (Oryza sativa) ZH-sg (Zhonghua 11 small grain mutant) with the accession number of CGMCC No. 2741; (2) hybridizing the small grain CMS line with large grain or normal grain restorer line hybrid rice for seed producing; (3) carrying out mechanized seed production of mixing sowing and mixing harvesting by utilizing small grain CMS line hybrid rice; (4) seed cleaning and separation after mechanical harvest. The invention can save a large amount of seed production field, reduce the investment of labor force in seed production, simplify the operation procedure and reduce mechanical admixture, storage and transportation cost and buying cost of hybrid rice seeds for rice farmers.
