为了丰富种质资源,加强品种选育工作,我们对从美国引进的花生属的几个野生种在进行观察的同时,并与花生栽培种四大类型代表品种进行了杂交,以探索其杂交亲和性,杂种优势及后代遗传变异规律,为利用野生种质资源提供理论依据。一、材料与方法 1979年7月下旬在温室采用花生栽培种四大类型代表品种做母本,以A.mo In order to enrich the germplasm resources and strengthen the selection and breeding of varieties, we carried out the observation of several wild species of the genus Peanut introduced from the United States, and crossed with the four representative varieties of peanut cultivars to explore their hybrid parents And sex, heterosis and genetic variation of offspring, to provide a theoretical basis for the use of wild germplasm resources. First, materials and methods In late July 1979 in the greenhouse using peanut cultivars four representative types of female parent, A.mo
