摘    要: 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。

关 键 词:大豆  遗传多样性  产量变异

Abstract:There is a increasing concern on the impacts of crop genetic diversity on production. This paper tries to explore the effects of genetic diversity on yield and yield stability of soybean production in China. A just-pope production function that incorporates genetic diversity as explanation variable is devel- oped and estimated using time-series and cross-section provincial level data. The estimated results suggest that the relationship between yield and genetic diversity presents a parabola pattern. The results also sug- gest that the variance of yield has a significant positive relationship with genetic diversity. The key conclu- sions of this study are that genetic diversity is the essential substance base for breeding and improving cul- tivars and the only way to guarantee the sustainable production of soybean is to strategically safeguard and conserve bio-diversity of soybean.
Keywords:Soybean  Genetic diversity  Yield variance
