摘　　要：通过对本所近年来选育出的8个亚麻高产、抗病品种(系)的株高、分枝数、单株桃数、单桃粒数、单株粒重等5个主要数量性状进行相关遗传力及通径分析,结果表明:单株桃数与单株粒重的相关遗传力最高并大于单株粒重的遗传力,且对单株粒重的直接作用最大。单株桃数作为间接选择性状更有效。Correlated heritability study and its path analysis of five major quantitative characters eg. plant height, bifurcation, fruit number per plant, grain number per fruit, kernals weight per plant of eight high yield and disease resistant varieties developed in the institute in recent year showed that correlated heritability of fruits per plant and kernels weight per plant was the highest. To use fruit number per plant as an indirect selection indicator will be more effective.
