In this paper we proposed to evaluate 53 pear genotypes collected in the germplasm collection of the Research Institute for Fruit Growing Pitesti, Romania regarding the behaviour to the main diseases and pests, in order to identify potential genitors for future breeding work. The evaluation was carried out between 2020 and 2022 after a scale from 1 (no symptoms) to 9 (very sensitive). The results obtained showed that there are enough sources of genes for resistance, as follows: 'Cu miezul roșu', 'Anțig', 'Harbuzești', 'Para lui Niță', 'Pere gutui', 'Tudor', 'Haydeea', 'Argessis', 'Romcor', 'Cristal', 'Paradise', 'Euras', 'Aniversare' cvs. for resistance/tolerance to fire blight; 'Ervina', 'Romcor', 'Para lui Niță', 'Cristal', 'Tudor', 'Mustoase', 'Paradise', 'Daciana', 'Carpica', 'Republica' cvs. for resistance/tolerance to pear scab;'Paradox', 'Corina', 'Pepenii', 'Haydeea', 'Argessis', 'Untoasă de Târgu Mureș', 'Isadora' - for the resistance/tolerance to Psylla. Some of these cultivars ('Cu miezul roșu', 'Isadora', 'Monica', 'Haydeea', 'Ervina', 'Cristal', 'Euras', 'Paradise') have already been introduced into artificial hybridization carried out in the last years.
