摘要
野生大豆是栽培大豆品种改良的基因来源。野生大豆与栽培大豆杂交是未来大豆新种质增加的有效途径。野生大豆具有高蛋白、多花多荚和抗逆性强等优良特性。研究证明大豆育种上通过种间杂交方法创造出具有野生血缘的育种中间材料,可以选育出高蛋白大豆新品种。深入探索野生大豆高蛋白资源在大豆种间杂交后代的遗传规律,可以为大豆特异种质创新提供理论依据。
Wild soybean has been thought to be an important genetic resources because it has a high content of protein,high productivity of pods and/or seeds and high resistance to environmental stress.Many studies of the introgression of wild germplasm with high-protein into cultivated soybeans by crossing between wild and cultivated soybeans have demonstrated that the wild germplasm introgression is a very effective method to develop new soybean germplasms with high-protein.Further study hereditary laws in descendants of interspecific cross between wild and cultivated soybeans with high-protein will provide theoretical basis on expanding the genetic background in soybean breeding.
