本文研究了秣食豆与其它类型大豆间杂种后代的育种效果及遗传潜势。结果表明,含有秣食豆血缘的组合,植株高大繁茂,粒茎比小,单株荚数和单株粒数多,但百粒重小。含有秣食豆种质的类型间组合,内在遗传潜势最大。秣食豆种质向栽培大豆渗入,能显著增加杂交后代单株荚数和单株粒数,提高主要产量性状的选择潜力。只要亲本选配得当,株高和百粒重等性状在F_2即可出现栽培大豆类型。含有秣食豆血缘的组合可用于选育纳豆等特用大豆新品种。
In this paper, we studied the breeding effect and genetic potential of hybrid progenies between captive beans and other types of soybean. The results showed that the combination of blood beans containing beans, tall and lush plants, small stalk ratio, pods per plant and the number of grains per plant, but a small weight of 100. The combination of the types of Giant bean germplasm has the highest intrinsic genetic potential. Mung bean germplasm infiltrated into cultivated soybean can significantly increase the pods per plant and the grain number per plant of the hybrid progeny, and improve the selection potential of the main yield traits. As long as the parents are properly matched, the cultivated soybean type can appear in F_2 with the characters of plant height and 100-grain weight. The combination of soy beans with soy beans can be used for breeding special soy bean varieties such as natto.
