摘要: 本文对13个四川小豆(V. angularis)地方品种株高、有效分枝、单株荚数、单株粒数、单荚粒数、百粒重、荚长和单株产量(Y)进行了通径分析。结果表明:单株荚数、百粒重对单株产量的直接效应和决定系数极显著,其它性状直接效应不显著且主要通过这两个性状起间接作用。故在小豆育种和栽培中,以选择单株荚数和百粒重为主,并协调两者间的关系,对取得高产具有重要作用。

Abstract: Path analysis was conducted for the plant height(x1), the number of effective branches(x2), the number of pods Fer plant(x3), the number of grains per Plant(x4), the number of grains per pod(x5), 100-grains weight(x6), the length of pod(x7) and the grain weith per plant(Y) in 13 local varieties of small bean in Sichuan. The results indicated that the direct effects were the highest for x3, x6, the direct effects of other traits were small, Total effects of x3, x6 for Y were not the highest, other traits indirectly contributed to Y through x3, x6, In order to get higher yield, x3, x6 were the most important to the breeding and cultivation.
