摘要
应用相关和通径分析,分析了四川54个地方品种的16种数量性状与产量(株粒重)间的关系。结果表明:株粒数、完全粒、百粒重和总荚数与产量有密切的正相关。其它性状则与产量相关不显著。16种数量性状对于产量的总决定系数为0.959;通径分析表明:株粒数、百粒重于产量的直接效应最大。由这一结果,讨论了这些特性于大豆育种的意义。
The relation between sixteen characters of soybean local varieties in sichuan with yield/plant was studied by means of relative and path analysis, The results indicated that there was notable relation between seeds/plant, 100 seeds weight, full seed and total pods/plant with yield/plant But the relation between other factors with yield/plant was not notable. The total decisive coefficient was 0.959, Path analysis indicated that direct effect of seeds/plant, 100 seeds weight to yield/plantwas the most important.
