本试验对28个豌豆(Pisum Sativum Lin.)地方品种单株荚数(x_1)、单株粒数(x_2)、百粒重(x_3)、株高(x_4)、第一荚结位(x_5)和单株籽粒产量(y)进行了通径分析.结果表明:单株粒数和单株荚数对单株产量的贡献很大,其中,表型的直接效应,单株粒数最高;遗传的直接效应,单株英数最高,且单株粒数和单株英数相互依存.百粒重对单株产量的贡献较次.株高和第一荚结位更次.这启示人们,在豌豆育种和栽培中,以选择单株荚数、单株粒数为主,适当兼顾百粒重及其它,对取得高产是很重要的.
In this study, the genetic diversity of 28 pea (Pisum Sativum Lin.) Cultivars including pods per plant (x_1), per plant (x_2), per plant (x_3), plant height ) And single grain yield (y) were studied.The results showed that single grain number and pod number per plant contributed greatly to the yield per plant, of which the direct effect of phenotype and the highest grain number per plant were observed. The direct effect of heredity, the highest number of plants per plant, and the number of grains per plant and the number of plants per plant were interdependent. The contribution of 100-grain weight to the yield per plant was lower than that of the first plant. , Pea breeding and cultivation, in order to choose the number of pods per plant, the main grain per plant, taking into account the balance of 100 and other, to obtain high yield is very important.
