目前,苏联大豆育种目标主要攻高产、稳产,同时也注意高蛋白质及高油分含量的选择。由于采用了在不同生态条件下,对杂种后代进行现代化的栽培技术和定向培育,近年来选出了有最适宜的生育期和对温度要求低的早熟、快熟品种;有适于南方栽培区草田复种和休闲地粒用快熟高产品种;有适于机械化栽培以及能抵抗普遍发生流行性病虫害的品种。在高产育种方面主要选择对不利因素的抗性,使植株保持最适宜的应变能力,在研究提高产量遗传潜力的途径上,研究了每荚粒数、百粒重、有效节数、成熟期荚数和豆荚不裂开等性状,并注意选择抗倒伏和抗茎折、结荚部位高、成熟整齐等性
At present, the goal of soybean breeding in the Soviet Union mainly focuses on high-yielding and stable production while also paying attention to the choice of high-protein and high-oil content. Due to the adoption of modern cultivation techniques and directional cultivation of hybrid offspring under different ecological conditions, in recent years, the most suitable growing period and the early maturing and quick-maturing varieties with low temperature requirements have been selected; Grassland crop and leisure grain with fast-growing high-yield varieties; suitable for mechanized cultivation and resistance to prevalence of pests and diseases of the popular species. Main resistance to unfavorable factors in high-yielding breeding and plant adaptability to the most appropriate strain. To study the ways to improve the genetic potential of yield, we studied the effect of per pod grain number, grain weight, effective node number, mature pod Number and pod does not crack and other traits, and pay attention to choose anti-lodging and anti-stem, pod parts of high, mature and tidy
