The assessment of variability in fruit quality traits among pear genotypes is essential for the characterization of genetic resources and for supporting breeding strategies aimed at improving fruit quality. This study evaluated several morphological and qualitative parameters, including fruit weight, soluble sugar content, and pulp firmness, in a set of pear cultivars and local populations cultivated in western Romania. The results indicated significant differences among genotypes. Fruit weight ranged from 149.52 g (‘Williams’, used as control) to 288.84 g (‘Santa Maria’), while soluble sugar content varied between 12.77 °Brix and 17.30 °Brix, with ‘Fizești’ and ‘Margaret’ genotypes exhibiting the highest sugar levels. Fruit firmness values ranged from 3.43 N (‘Fizești’) to 5.53 N (‘Williams’). The observed variability highlights a substantial genetic diversity within the analyzed material, offering valuable perspectives for future selection and breeding programs targeting pear cultivars with superior qualitative attributes.
