摘要: 本文通过对国内外许多学者关于产量构成因素及其他性状对产量的通径分析中普遍存在的一些问题的分析,明确了农作物产量由产量构成因素决定,理论上产量构成因素对产量的决定度为100%。产量构成因素是影响产量的直接性状,而其他通过产量构成因素间接影响产量的性状为间接性状。间接性状不存在对产量的直接作用,只能通过产量构成因素间接影响农作物产量。

关键词: 通径分析, 农作物, 产量构成因素, 性状

Abstract: It is pointed out in this paper that some problems exist in many other works concerning the crop yield components and the path analysis method.It is also put forwardthat the correct conclusion can be obtained only when the path analysis method is conformedto the biological laws,otherwhise,a incorrect result violating the biological laws will beobtained.The result also shows that the yield is decided by the yield components and thedetermination degree by the yield components ought to be in the theory.The yield components are the traits having direct effect on the yield and the other traits are ones havingindirect effect on the yield.

Key words: Path analysis, Yield components, Characters, Biological laws
