遗传多样性理论是目前国际上农学与经济学界研究的热点领域之一、本文在总结借鉴国内外研究方法与成果的基础上，以遗传学理论为指导，分析了我国大豆主要生产省份历年来所推广品种的类型及其遗传基础的变化情况，并从经济学的角度来验证大豆遗传多样性对大豆产量及其稳定性的影响，得出了品种亲本系数（ＣＯＰ）与产量间呈抛物线关系、且与产量稳定性间呈负相关的结论，并对其政策含义做了讨论。
The theory of genetic diversity is one of the hot research fields in agronomy and economics in the world at present. Based on the summary of the research methods and achievements both at home and abroad, with the guidance of the theory of genetics, this paper analyzes the main producing provinces in China over the years The types of the varieties to be popularized and the changes of their genetic basis, and the effects of soybean genetic diversity on soybean yield and its stability were verified from the economic point of view. The relationship between the coefficient of yield (COP) And negatively correlated with the yield stability. The policy implications were also discussed.
