The results of monitoring phenological characteristics of 12 autochthonous apple cultivars were summarized during the years. Morphological fruit characteristics were described and chemical composition were analyzed. In 4 autochthonous cultivars, resistance to low temperatures was evaluated based on: a) content of macronutrients (N, P and K) and their relation in one year old branches and b) dynamics and content of total anthocyanins in the bark of one year old branches during winter dormancy. Resistance to drought was analyzed according to the capacity of leaves to retain water. Resistance to economically important diseases and pests, ebullience and fruitfulness was describably evaluated based on visual observations and experiences. Based on already given information, the conclusion about possibility of using autochthnous cultivars for organic apple orchards was made.
