The main objective of the works was to identify genotypes with increased tolerance or resistance to pathogens under the current climatic conditions for their extension into the culture. The trials on 20 apricot cultivars and selections were carried out in the orchard, during 2020-2022, under natural infection conditions, tracking the frequency and intensity of the attack on different organs of the plants and how they were influenced by current climate changes. These studies demonstrated that the most resistant to Monilinia laxa, Cytospora cincta and Stigmina carpophila were 4 cultivars ('Mamaia', 'Roșii de Mărculești', 'Olimp' and 'Elmar'), while 3 other cultivars ('Litoral', 'Pionier' and 'Sirena') had sensitivity to the attack of Cytospora cincta and Stigmina carpophila. The biggest losses caused by frost were recorded during the winter/spring of 2021 in terms of damaged fruit buds: 90% on 'Comandor' 88% on 'Pionier', 85% on 'Roșii timpurii' and 'Sulina', 67% on 'Sirena' and 65% on 'Mari de Mărculești'. The nursery has propagated resistant cultivars and selections, while the most valuable genotypes are grown in commercial orchards.
