  • Variation in germinating rate, seedling rate and growth of the seeds with different plumpness of hybrid rice varieties Liangyoupeijiu, Xieyou7954 and Xieyou9320 was studied. The results showed that the germinating rate and the seedling rate were significantly positive correlated with seed plumpness. The lower plumpness of rice seeds was, the lower their germinating rate and seedling rate was. The germinating rate of the rice seed floating on water was 35%-68% , and the seedling rate was 36%-62%. However, the germinating rate of the seeds sinking in 1.10 gravity solution was more than 97%, and the seedling rate was more than 75%. Tiller capacity and dry matter of the seeds floating on water was lower than that of the seeds sinking in 1.10 gravity solution. Efficiency of seed selection in rice production was discussed.
