摘　　要：[目的]初步筛选出抗相似穿孔线虫的香蕉品种。[方法]通过在温室中采用盆栽接种方法,分别测定了13个香蕉种资资源对相似穿孔线虫种群1和种群2的抗病性。[结果]接种种群1的处理中,云南粉蕉属高抗品种,皇帝蕉(AA)属抗病品种,有7个品种表现中抗;接种种群2的处理中,没有高抗或抗病品种,有9个香蕉品种表现中抗,巴西蕉(AAA)为高感品种。[结论]试验结果为寻找抗相似穿孔线虫的香蕉品种或基因奠定了基础。[Objective] The aim was to screen out banana germplasm resources with resistance to Radopholus similes. [Method] The resistance of 13 banana germplasm resources against Radopholus similis population 1 and population 2 were identified in greenhouse through pot inoculated method. [Result] The results show that 1,1 and 7 varieties of 13 tested varieties were of high resistance,resistance and middle resistance to the process of population 1. Nine varieties of 13 tested varieties were middle resistance,and Musa AAA Giant Cavendish cv. Baxi was high susceptibility,and not found high resistance and resistance varieties to the process of population 2. [Conclusion] The results lay the basis for find banana varieties or gene with resistance to Radopholus similes.
