测定了约4000份栽培种材料(包括品种、引种材料、品系和射线诱发的突变体)对花生矮化病毒的抗性。结果表明全部材料对花生矮化病毒的侵染表现易感。其中有21份材料较其他材料受害为轻。另外,对搜集的90份野生种(其中包括Rhijomatosae区系55份,Arachisl7份Erectoides 16份和Caulorhigae、Ext-ranervosae区系各一份)亦进行了抗性测验。结果表明,Arachis、Caulorhi-gae、Erectoides和Rhigomatosae区 Resistance to peanut dwarf virus was determined for about 4,000 cultivars of material, including varieties, introductory materials, lines and radiation-induced mutants. The results showed that all materials were susceptible to peanut dwarf virus infection. 21 of them were harder than the other materials. In addition, 90 wild species collected, including 55 Rhijomatosae flora, 16 Arachis species Erectoides and one Caulorhigae and Ext-ranervosae flora, were also tested for resistance. The results show that Arachis, Caulorhi-gae, Erectoides and Rhigomatosae districts
