摘 要 ：遗传资源搜集原则是通过种子采集追求样本具有最高程度的遗传多样性。为了合理而有效地搜集野生大豆资源，近年来通过野生大豆居群考察和遗传多样性分析，初步明确了野生大豆资源居群的遗传多样性分布动态：遗传多样性地理的和生态的区域性、生态系统内居群的遗传相关性、及各种生境下居群遗传多样性差异。从理论上奠定了野生大豆资源合理有效搜集的依据。根据居群遗传多样性的分布规律，初步建立了居群野生大豆资源的搜集策略和方法。

Abstract:The object of collecting for crop genetic resources is to obtain the highest degree of genetic diversity in the seed samples. In order to effectively collect wild soybean germplasm resource, we surveyed and analyzed genetic diversity in the natural populations of wild soybean in recent years, and understood the patterns of genetic diversity in wild soybean populations: including geographical and ecological regionalities of genetic diversity, genetic relationship among populations within ecosystems, and the degrees of genetic diversity in wild soybean populations under various habitats. These results have become a theoretical fundament in guiding collecting of wild soybean germplasm. According to the distribution of genetic diversity for wild soybean populations in various habitats, we preliminarily established fundament principia and methods for effectively collecting wild soybean germplasm resources.
