In this research, Gufeng A and Minhui 3301 were used as experimental materials to compare the differences in growth period, fertility, yield and yield components of sterile line Gufeng A under the two cultivation methods of direct seeding and seedling transplanting. The results showed that, compared with the transplanting method, the seed production period of direct seeding method was shortened by about 3 days, and the flowering period was more concentrated. The flowering rate, stigma exsertion rate and outcrossing rate before noon were significantly improved; the maximum number of seedlings, effective panicle and seed setting rate, agricultural traits were also greatly improved, and the yield increased by 5.76%. The income per hectare is up to 6,786 yuan, which was increased by 10.17%.
Key words: hybrid rice; Guyou3301; direct seeding of female parent; seed production; yield
