自本世纪六十年代以来,花生野生种质资源的研究愈来愈受到人们的重视。其原因:一、花生育种面临的主要问题之一就是遗传基础狭窄,育种者迫切需求有新的“基因源”充实于栽培种中去,而野生种质资源却是这些“迫求基因”最重要的来源:二、花生野生种多是二倍体,除具有良好的抗性、适应性外,且是研究花生细胞遗传学最好的材料;三、利用花生野生种间杂交,来推断花生栽培种的祖先,以 Since the sixties of this century, the research of peanut wild germplasm resources has drawn more and more attention. The reasons are as follows: First, one of the major problems peanut breeding faces is that the genetic basis is narrow, breeders are in urgent need of new gene sources enriched in cultivated species, and wild germplasm resources are the most important Important sources: Second, the peanut wild species are diploid, in addition to having good resistance, adaptability, and is the study of peanut cytogenetics the best material; Third, the use of wild peanut interspecific hybridization to infer peanuts Ancestors of cultivated species
