Abstract: Nine middle-season hybrid rice varieties approved and certificated by Fujian Province were compared with "Guyou 3301" as control at Anyuan Town, Ninghua County. The results showed that yield of "Liangyou 667", "Fuliangyou 366", "Guangyouming" 3186, "Guangliangyou 676" and "Hua 2 you 3301" were all increased than that of "Guyou 3301" with significant level and could be extended in local areas. Yield of "Taifengyou 3301", "Guyou 353", "Zhongzheyou No.8" and "Zhongzheyou No.10" were not significantly increased or decreased, and could be selectively planted when considering the factors of their high quality or high disease-resistance.
