The aim of study was to evaluate the basic characteristics variability of wild apple (Malus domestica Borkh.) seedlings selected collection. For this experimental study were applied 77 natural seedlings in different regions of Slovakia located during previous exploration. For the selection and evaluation purposes a health status was regarded as the most important criterion. Based on morphometric analysis was determined the average weight of fruits in range of 16.13 to 197.59 g, height of fruit from 29.55 to 74.04 mm, fruit width from 36.85 to 78.43 mm, depth of stalk cavity/calyx cavity  2.04- 16.1 mm / 1.22 – 11.69 mm, the fruit core height /width in ranges of 11.24 – 25.86 mm / 13.72 – 30.86 m, respectively. By correlation analysis were determined the correlation coeffi cients between the evaluated traits. Very strong degree of linear dependence was determined between the fruit weight and height (0.902) / width (0.959). A strong degree of dependence was found between the height and width of the fruits (0.861), depth of stalk and calyx cavity (0.722), fruit weight and depth of the stalk cavity (0.713). Among the other traits occurred only a moderate degree of dependence..  Signifi cant differences were determined between the seedlings in the shape of fruit, color of fruit fl esh and other features as well. The studied natural population of seedlings is suitable for selection of important and interesting genotypes in term promising genetic resources for breeding of new varieties as well as for direct use in practice.
