花生分布很广,在世界六大洲的温暖地区都有种植,主要栽培于亚洲、非洲和美洲。各地品种之间存在着明显差异。每个地理群内都有突出优良的遗传资源。加强品种鉴定,阐明各地品种的遗传特异性,进一步弄清各品种间的关系,对扩大和丰富花生的遗传资源及引种有其十分重要的意义。
Peanuts are widely distributed and planted in warm areas of all six continents, mainly in Asia, Africa and the Americas. There are obvious differences among varieties. Outstanding high quality genetic resources within each geographical group. It is of great significance to strengthen the identification of cultivars, elucidate the genetic specificities of the cultivars in different regions and further clarify the relationships among the cultivars, and to expand and enrich the genetic resources and introduction of peanut.
