Shrnutí:	Common plum (Prunus domestica L.) represents the main fruit species in South-East Europe, both as cultivated surface and fruit production as well. In Romania, the common plum is grown on more than 35.000 ha, its fruits being appreciated for fresh consumption or processed, as a source of fitonutrients and active principles. Therefore, nowdays there is an real interest for genetic resources evaluation, assortment inprovement, and growing technologies or sequences modernization. The work present the rezults on the behavior of some common plum genotypes on natural infections with patogenic fungi. 94 de plum genotypes (34 from Romania and 60 from abroad) with ages ranging between 4 and 7 years, grafted on 7 rootstocks, were evaluated as regard their behavior to natural infections with patogenic fungi such as moniliosis - Monilia laxa, red spot - Polystigma rubrum și micotic shoothole - Stigmina carpophila. At the end of the study was found that among the trees aged of 4-5years, the most sensitive genotypes were: ˈJubileumˈ (VSI%=0.390), ˈSW H 0834ˈ (VSI%=0.490) and ˈHanitaˈ (VSI%=0.670). Among the trees aged of 6-7 years, the most sensitive genotypes were: ˈCentenarˈ (ISV%=0.445-0.883), ˈAndreeaˈ and ˈRomanțaˈ (VSI%=0.388-0.638), ˈCacacnska Lepoticaˈ (VSI%=0.374-0.416), ˈTimocanskaˈ (VSI%=0.425) and ˈJojoˈ (VSI%=0.459-0.487). Therefore, the mentioned genotypes needs with priority integrated phytoprotection.
