Sweet passion fruit (Passiflora alata Dryander) from ten different sources were evaluated for the severity of anthracnose (Colletotrichum gloeosporioides Penz.) and their fresh weight losses when stored in two environmental conditions: cold storage (5ºC and 90% R.H.) and room temperature (23±1ºC and 65±5% R.H.). Seed plants were established from ten sources proceeding from the Central of Food Supply of São Paulo State - CEAGESP (sources A, B e C), Viçosa-MG (source D), Tomé-Açu-PA (source E), Itacoatiara-AM (source F), Ouro Preto d'Oeste-RO (source G), Domingos Martins-ES (source H), Pontes e Lacerda-MT (source I), Rondonópolis-MT (source J) and stem cuttings were collected from the best plants to produce the asexual matrix plants. Unriped fruits produced in Distrito Federal, Brazil, were harvested from plants obtained by stem-rooted cuttings. All origins were collected in wild conditions, except A, B, C and E sources. Fruit evaluations were done by determining their weight fresh matter after 0, 3, 6, 9 and 12 days after harvesting, whereas the anthracnose severity (% of fruit area with lesions) and incidence (% of infected fruits) of other diseases were evaluated after 12 days of storage. The anthracnose was less severe on fruits from sources I and G, however, this disease shown less severe attack when fruits were stored in cold conditions. After 12 days of storage at room temperature, the fruit sources G and A, had fresh matter losses of 16,68% and 17,86% while in cold storage the fresh matter losses were 7,71% and 6,61%, respectively. The percentage of fresh matter loss of G, A, E, J and F fruit sources was less in room temperature when compared with other sources. It was observed after 12 days at cold storage, that the fresh matter loss shown an average of 9,78%, which is approximately twice lower the storage at room temperature (22,06%).
