花生栽培存在高产与不抗病的矛盾,在育种上需要具有高抗和适应强的“基因源”渗入栽培种。可是在育种中却面临着遗传基础狭窄的问题。花生属植物资源,具备这种“基因源”的条件。如何使野生种的抗性基因引入栽培种已为花生育种者所关注。 花生原产于南美洲,本世纪三十年代人们就已开始对花生属植物资源的利用研究.1935年Hull及Caruer以栽培种和A.glabrata杂交,未得到杂种;1946年Gregory报道他试图用花生栽培种与两个野生种(A.Villosalicarpa及A.diogoi)进行种间杂交,也未成功;
Peanut cultivation there is the contradiction between high yield and non-resistance in the breeding needs of high resistance and strong adaptability of the “gene source” infiltration cultivars. However, in breeding, it is confronted with the problem of narrow genetic basis. Peanut plant resources, with this “gene source” conditions. How to make the introduction of wild type resistance genes into cultivated species has been of concern to peanut breeders. Peanuts originated in South America, people began to study on the utilization of peanut resources in the thirties of this century.In 1935, Hull and Caruer crossed with A. glabrata without hybrids; in 1946, Gregory reported that he tried to use Peanut cultivars also failed to succeed in interspecific hybridization with two wild species (A.Villosalicarpa and A.diogoi)
