野生大豆(G.Soja)与栽培大豆(G.max)是大豆属(Glycine)的两个种。它们的染色体数目相同(2n=40),二者杂交结实正常。野生大豆长期以来在不同生态条件下繁衍继代,形成了适应不同环境条件的各种生态类型,并具有栽培大豆所没有的某些特殊性状。因而野生大豆这样珍贵的种质,将成为抗性育种、高蛋白育种甚至丰产育种杂 G.Soja and G.max are two species of Glycine. They have the same number of chromosomes (2n = 40), and their hybridization is normal. Wild soybean has long been multiplied in different ecological conditions, forming a variety of ecological types to adapt to different environmental conditions, and has some special traits that are not found in cultivated soybean. Therefore, the precious germplasm of wild soybean will become resistant breeding, high-protein breeding and even breeding
