Summary Within a blueberry research program in SW Spain, five rabbiteye ( Vaccinium ashei Reade) and nine southern highbush ( Vaccinium corymbosum L.) commercial cultivars along with 38 hybrid plants, produced by crossing highbush and rabbiteye cultivars, were used. The differences in the fruit size and the picking scar size among the plants, and the annual differences within each plant were studied. No significant differences were found in the fruit length, width, weight and the picking scar size between the rabbiteye and the southern highbush cultivars, and neither between the cultivars and the hybrid progeny. However, significant differences were found among the cultivars and among the hybrid plants. The picking scar size correlates better with fruit width and weight than with fruit length, although correlation values are not high. Thus, outliers were observed, some of them interesting to be selected for having large fruits and narrow scars. The ratio between the picking scar and fruit width shows significant differences among subsequent years in many hybrid plants.
