Cowpea aphid-borne mosaic virus (CABMV) is the main pathogen that affects passion fruit, causing woodiness disease in Brazil. The identification of sources of resistance in Passiflora is necessary for the development of resistant cultivars. The objective of this work was to evaluate the reaction of eight species of Passiflora to CABMV and to verify leaf anatomical changes caused by CABMV. Inoculations were performed and symptoms were evaluated until 55 days after inoculation using a scale ranging from 1 (without symptoms) to 4 (highly susceptible). Simultaneously, leaves from infected and control plants for anatomical analysis were collected. The severity of the disease was calculated using the disease index (DI%) and the means were grouped using the Scott-Knott test. The wild species Passiflora malacophylla, P. setacea and P. suberosa were classified as resistant to CABMV. In contrast, P. alata and P. edulis were susceptible to the virus, with DI values of 58.2 and 51.9%, respectively. Leaf anatomical changes were more drastic in P. edulis and P. alata. In P. edulis, the infection resulted in changes in the organization of the vascular bundles. Resistant wild species showed few anatomical changes. The resistance found in wild species opens the prospect of performing interspecific crosses.

豆蚜虫传播的花叶病毒 （CABMV）是影响百香果的主要病原体，在巴西引起木质病。鉴定西番莲中的抗性来源对于开发抗性品种是必要的。这项工作的目的是评估八种西番莲的反应并验证CABMV引起的叶片解剖变化。进行接种并使用1（无症状）至4（高度易感）的等级评估症状直至接种后55天。同时，收集感染和对照植物的叶子进行解剖分析。使用疾病指数（DI％）计算疾病的严重程度，并使用Scott-Knott检验对平均值进行分组。野生种西番莲malacophylla，P. setacea和P.木栓被列为耐CABMV。相反，P。alata和P. edulis易感病毒，DI值分别为58.2％和51.9％。食用假单胞菌和阿拉善假单胞菌的叶片解剖变化更为剧烈。在可食假单胞菌中，感染导致血管束组织的变化。抗性野生物种几乎没有显示解剖变化。在野生物种中发现的抗性打开了进行种间杂交的前景。
