Summary: The results of investigations of growth, fruitfulness and fruit quality of five apple cultivars (Hi Early, Elstar, Alkmene, Prima, Golden Delicious clone b) grafted on rootstock M.26, MM.106 and MM.106 with M.9 as interstock, showed that interstock decreased trees vigor and increased fruitfulness. In the semi-humid area of continental Croatia the best fruitfulness was occurred in cvs. Golden Delicious clone b and Prima. The lowest yield was found in cv. Hi Early. Average fruit mass and fruit quality was satisfactory. Leaf analyses showed genetic specificity of examined cultivars.

Keywords: apple cvs., rootstock, ecological conditions, ecophysiological capacity,fruit quality

Research goals: The aim of the research is to work out and improve new technology in apple growing in high density planting. Efforts will be directed towards the increase of fruitfulness, better quality of fruit and lower production costs. Suitable combinations of cultivars on rootstocks and interstock in various ecological conditions will be assessed. Research will contribute to improvement in both projecting new orchards and apple production.
