[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/hm2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 research aimed to study the economic traits of 33 Chinese rice varieties planted in Angola. [Method] With 28 middle-season indica rice and 5 conventional japonica rice varieties as test materials in China, they were divided into 3 groups and planted in Luanda Region. The adaptability, high yield and major economic traits of rainy season planting in Luanda were analyzed . [Result] Ten indica rice varieties had good adaptability and high yield. The effective panicle number, total grain number per panicle, 1000-grain weight and ratio of grain to straw of medium indica varieties were normal, but the whole growth period was obviously shortened, and the seed setting rate And the yield was about 11.5t / hm2. The middle-season indica hybrid rice combination Wandao 51 (waxy) and yellow flower Accounting for good adaptability and high yield; Japonica varieties less adaptable. [Conclusion] The results of this study provided a technical reference for planting Chinese rice varieties in Angola.
