摘要
通过对38个杂交晚稻新组合F1代的单株有效穗数、每穗总粒数、每穗实粒数、千粒质量和株高整齐度与产量的相关分析和通径分析,发现影响杂交晚稻产量最重要的因子是每穗实粒数;其次是单株有效穗数、千粒质量和株高整齐度;每穗总粒数对产量的影响不显著。
Correlation analysis and path analysis were made on five main traits and yield by using 38 combinations of hybrid late season rice. The results show that filled grain numbers per panicle is the most important factor and the following factors are panicle numbers per plant, 1000-grain weight and evenness degree of plant height; Total grain numbers per panicle is not obviously correlated with yield.
