大豆相关农艺性状对产量的遗传贡献率研究结果表明,各农艺性状对产量的表现型方差有不同程度的贡献。荚数对产量的加性贡献率较高,为52.89%,且在4个亲本中对产量的加性效应具有最大贡献,可考虑作为亲本产量加性效应的间接选择指标;对产量加性效应贡献最大的农艺性状因不同亲本而异,表明各亲本具有其独特的遗传和发育特性。荚数对产量的显性遗传方差贡献率较高,为22.45%,且在14个组合中对产量的显性效应具有最大贡献,可作为间接选择组合产量显性效应的指标。

Heredity contribution rate of agronomic traits to yield of soybean was studied.The result showed that various agronomic traits had contribution to phenotype variance of yield in different degrees.The additive contribution rate of pods per plant to yield was high,reached 52.89%,and it had the biggest contribution to additive effect of yield per plant in 4 parents.It might be considered as the indirect selection index of the parent yield additive effect;the agronomic traits which had the biggest contribution to yield additive effect varied in different parent.It indicated that various parents had its unique heredity and growth traits.Dominance genetic variance contribution rate of ods per plant to yield was high,reached 22.45%,and it had the biggest contribution to dominant effect of the yield in 14 combinations,and might be considered as the target of dominant effect of the indirect selecting combination yield.
