【摘要】 我国有着极为丰富的大豆品种资源,为扩大大豆生产、提高大豆单产,从利用特异大豆种质拓宽大豆的生态适应性、提高大豆产量等几个方面讨论了大豆遗传多样性对大豆产量改良的重要性。并结合生产条件的变化和大豆品种资源研究的进展等因素,提出近期和未来对大豆产量改良可能起到重要促进作用的一些性状或侧重的研究方向更多还原

【Abstract】 Genetic diversity provides breeders the possibility of improving soybean yield. Variation in maturity made it realizable to enlarge possible soybean production area. Diversity in various resistance/tolerance and rich branches have been playing the key role in soybean yield enhancement. Special types of male sterility, ideal root structure, higher outcrossing percentage, and GH effect insensitive genotypes are also believed to contribute a great deal to soybean yield improvement in the future.更多还原
