摘　　要：[目的]筛选适合尼日利亚的优质、高产水稻品种。[方法]从中国引进的8个高产、优质、高抗杂交水稻新组合作参试种,以当地种植的主要水稻品种为对照进行试验,随机区组排列,收获前调查产量及其构成因素。[结果]对照的生育期最长,比中国杂交种长9-14 d。所有中国杂交水稻全部比CK极显著增产,增幅20.33%-68.69%。对照产量最低、穗大但粒少、千粒重较低,品质中下等,感稻瘟病等。引进的中国杂交水稻新组合表现为：高产、穗大、粒多、千粒重较高,品质上等,抗到中抗稻瘟病。[结论]建议尼日利亚引进进行示范、推广华优3号、两优363C、优36、黔优联合9号、汕优联合2号等品种。[Objective] The study aimed to screen out the rice varieties with high quality and yield that adapted to be planted in Nigeriz.[Method] In the induction test with randomized block arrangement,taking 8 Chinese rice varieties with high yield,quality and resistance as tested materials and the main rice varieties planted in Nigeriz as CK,the yield and its composition were investigated before harvest.[Result] The growth period of CK was longest,being 9～14 d longer than Chinese rice varieties.The yields of all Chinese rice varieties were significantly increased by 20.33%～68.69% than CK.CK had lowest yield,big spike with less grain,lower 1 000-kernel weight,the middle and low grade quality and the susceptivity to blast.While Chinese rice varieties had a high yield with big spike with more grain,higher 1 000-kernel weight,high grade quality and middle and high blast resistance.[Conclusion] The varieties such as Huanyou 3,Liangyou 363C,You 36,Qianyoulianhe 9 and Shanyoulianhe 2 were suggested to be introduced,demonstrated and popularized in Nigeria.
