中国是大豆的故乡,有着极其丰富的资源。它的近缘野生种——野生大豆(G.Soja)和半野生大豆(G·grucilis)资源令世界各国大豆科技工作者所瞩目。野生大豆蛋白质含量高、抗逆性强、分枝多、花荚数量大、单株产量优势强,是高蛋白育种的宝贵资源。近年来,国内外大豆育种工作者,特别是我国东北三省在栽培大豆育种研究的基础上,相继开展了野生大豆高蛋白基因改良,为栽培大豆的进一步研究创造了必要条件,已初见成效,并运用于生产。为了充分利用我省的高蛋白野生大豆资源,拓宽大豆遗传基础尽快选育出高蛋白大豆新品种,将资源优势变为育种优势,有必要弄清野生大豆资源蛋白质含量与地理分布、特征特性及其它性状的关系。
China is the hometown of soybean and has extremely rich resources. Its close relatives of wild species - G. soja and G. grucilis have drawn the attention of soybeans from all over the world. Wild soybean protein content is high, strong resistance, branching, flower pods large number of superior yield per plant, is a valuable resource for high-protein breeding. In recent years, domestic and foreign soybean breeders, especially in northeast China, have carried out the research on soybean high-protein genetically modified on the basis of the researches on cultivated soybean breeding, which has created the necessary conditions for the further study of soybean cultivation. And used in production. In order to make full use of high-protein wild soybean resources of our province and broaden the genetic basis of soybean to breed new high-protein soybean varieties and turn resource advantages into breeding advantages, it is necessary to understand the protein content and geographical distribution, characteristics and characteristics of wild soybean resources Other traits.
