约在一百多年之前,在花生属中,人们只知道有栽培花生(A.hypogaeaL.)一个种。花生属也正是通过栽培种的发现和广泛种植,而被载入了植物学的教科书中。近年来,随着人们对野生种质资源潜在价值认识的逐步深入,世界许多国家的花生育种工作者竞相到南美洲起源中心去考察搜集花生栽培种的野生近缘植物。目前,花生属已经成为一个包括了七个区系五十余个地区性的种属了。我国引进、保存的野生种质材料也已有二十余份。可以预期,随着对野生种质搜集、鉴定,以及细胞遗传学等方面研究工作的深入开展,至少在以下三个方面将取得积极成果。
About a hundred years ago, in the peanut genus, only one species of cultivated peanut (A. hypogaea L.) was known. It is also through the discovery and extensive cultivation of cultivars that Peanut was included in the textbook of botany. In recent years, with the further understanding of the potential value of wild germplasm resources, peanut breeders in many countries of the world competed in the origin center of South America to study the collection of wild relatives of peanut cultivars. At present, the genus Peanut has become a species that includes more than 50 regional species in seven areas. China imported, preserved wild germplasm materials have also been more than 20 copies. It is expected that with the further research on the collection, identification and cytogenetics of wild germplasm, positive results will be achieved in at least the following three aspects.
