ABSTRACT
The fruit–growing plantations are often attacked by pathogenic agents that generate significant damages. The control of the pathogenic agents, especially based on the pesticides utilization, is easily in application, with fast results, but at high costs. In the same time, there is a hazard for the environmental pollution and resistance / tolerance forms appear in pesticides. For these economic and ecological reasons other means of control utilization are necessary. In this context, the genetic resistance of the plants confronted with the attack of pathogenic agents is very much evolved, especially when it is correlated with a high quality and productivity. In this work results are presented regarding the genetic resistance of some peach and apricot cultivars, confronted with the attack of the fungus Taphrina deformans, Sphaerotheca pannosa and Podosphaera trydactila. The results obtained, allow the identification of the genetic sources with the resistance to diseases which is utilized in apricot and peach tree breeding programs at Research Station forFruit Growing Baneasa-Bucharest.
