摘　　要：育种工作者通过遗传改良大幅度提高了大豆的产量,同时农艺性状在遗传改良过程中也发生了很大的变化,产量随着育成年代的增加而增加,单株荚数和粒数对产量影响较大,叶面积随育成年代呈增加的趋势,子粒含油量随着蛋白质含量的增加而降低。大豆株高不应继续降低,应保持在0.8 m,否则成为产量的限制因子之一,因此进一步开展大豆在遗传改良过程中某些农艺性状及其与产量关系的研究,对选育大豆优良品种和高产栽培有一定的指导意义。Soybean yield were improved by genetic improvement, meanwhile, some agronomic traits were changed largely. Yield of soybean were increased with year it was released and it were influenced by pods and seeds number per plant. Plant leaf area was increased with years, fat content of seeds were increased as the protein content reduced. Plant height should not be reduced and keep at 0.8m. Otherwise, it may become a limited factor to influence yield of soybean. So, it is of value to further the study of relation between some agronomic traits and yield of soybean, for it will guide the breeding of excellent cultivas of soybean and improving cultivation of high-yield soybean.
