栽培大豆近缘野生种在生物学特性及植物学特征上均具有许多优良特性如:抗旱、抗病、耐寒、长日照反应不敏感;株高、繁茂,有效分枝多、荚多、粒多等是育种上非常宝贵的种质。近年来在大豆遗传育种研究上,特别注意以栽培大豆与近缘野生种杂交,试图探讨栽培大豆的起源进化及将野生种这些特性转移到大豆属的其它种,创造新的大豆种,为育种提供基础材料。 The wild relatives of cultivated soybean have many excellent traits such as drought resistance, disease resistance, cold tolerance and long-day response to insects, as well as high plant height, lush, more effective branches, more pods and more grains Etc. is a very valuable germplasm on breeding. In recent years, in the study of soybean genetics and breeding, special attention has been paid to the hybridization of cultivated soybean and its relative wild species in order to explore the origin and evolution of cultivated soybean and to transfer the properties of wild species to other species in Glycine so as to create new soybean species for breeding Provide basic materials.
