Abstract
Apricot is a stone fruit of the family Rosaceae (order Rosales), closely related to peaches, almonds, plums, and cherries. Apricots are cultivated throughout the temperate regions of the world. In the present study, 17 apricot genotypes were characterized for 32 morphological traits with respect to distinctiveness; uniformity and stability (DUS) test guidelines. The results displayed a high level of variability among all the genotypes. The fruit characteristics such as fruit size, shape, fruit volume, flesh and skin color which determines the quality and marketability of apricot exhibited huge variation. Moreover, the results displayed suggest that description of these varieties based on notes may be used as reference for protection of new varieties under PPV&FRA rules and can be used for comparison against new candidate varieties.
