[目的]研究33个中国水稻品种在安哥拉种植的经济性状表现。[方法]以中国的28个中籼稻和5个常规粳稻品种为试验材料,将其分成3组并种植在罗安达地区,分析其在罗安达地区雨季种植的适应性、丰产性和主要经济性状。[结果]10个中籼水稻品种具有较好的适应性和丰产性;中籼品种的有效穗数、每穗总粒数、千粒重和谷草比表现正常,但全生育期明显变短,结实率明显提高;杂交中籼特优721、荃香优512、Ⅱ优128和102S/4HZ021四个组合综合性状优良,具有约11.5t/hm^2的丰产潜力;常规中籼皖稻51（糯）和黄花占具有较好的适应性和丰产性;粳稻品种适应性较差。[结论]该研究结果为中国水稻品种在安哥拉地区种植提供了技术参考。

[Objective] The aim was to research economic characters of thirty-three Chinese rice cultivars in Angola.[Method] In the research,twenty-eight hybrid mid-indica rice cultivars and five conventional Japonica rice cultivars were classified into three groups and then grown in Luanda to analyze adaptability,fertility and major economic characters of the rice in rainy season.[Result] The research showed that of twenty-eight hybrid mid-indica rice cultivars,ten cultivars were of better adaptability and fertility,which are suitable to be grown in Luanda in Angola;productive ear number,total grain per ear,thousand-seed weight and ratio of grain to straw of the rice cultivars performed normally,but the whole developmental period shortened and seedling setting rate improved significantly.In addition,hybrid indica Teyou 721,Quanxiangyou 512,II you 128 and 102S/4HZ021 were of fertility potential at 11.5 t/hm2,which were all proved excellent in related characters in rainy season in Luanda of Angola.For conventional mid-season rice indica cultivars,Wandao 51 and Huanghuazhan were of better adaptability and fertility.In contrast,5 Japonica rice cultivars were of poor adaptability.[Conclusion] The research provided technical references for Chinese rice growing in Angola.
