摘要：

应用恢色关联度分析方法，对重庆三峡农业科学院配组而成的两个类型的籼稻组合主要经济性状与产量的关联度进行了分析，结果表明：穗、粒兼顾型组合产量与各性状的关联度按大小顺序依次为实粒数>结实率>有效穗>千粒重>全生育期，表明每穗实粒数的高低是影响该类型组合产量的主要因素，有效穗及各粒重次之；重穗型组合产量与各性状的关联度按大小顺序依次为有效穗>实粒数>结实率>千粒重>全生育期，表明有效穗是影响该类型组合产量的主要因素，每穗实数次之。

Abstract:

The correlation degree between economic traits and yield of two indica rice combination were studied by gray correlation degree analysis. According to the results, the correlation degree between yield and other traits of panicle and spikelet type could conclude as follows: number of filled grains > seed setting rate > number of efficient tillers > 1000-grain weight > whole growth period, which indicated that the number of filled grains was the major factor of the yield of this type of combination. The results of heavy panicle type were as follows: number of efficient tillers > number of filled grains > seed setting rate > 1000-grain weight > whole growth period, which indicated that the number of efficient tillers was the major factor of the yield of this type of combination.
