The investigations were carried out from 1989-1991 with the main aim of finding out which is the best way of tree training and pruning for peaches grown at high density in the greenhouse. For the study three cultivars, Golden Jubilee, Kijowskij Rannyj, and Redhaven were used. The rootstock was a peach seedling. The trees were planted at 2.5 m × 2 m spacing and trained with a central leader or as a bush tree. In order to limit their growth in the summer of each year light pruning was carried out several times. The training strongly differentiated the tree growth and first yield. Bush type trees grew more strongly and had a smaller yield than trees with a central leader. The latter training made it possible to limit the size of the crown and to maintain a balance between the tree growth and its yields. Redhaven was to be most suitable cultivar for greenhouse cultivation owing to its weak growth and high yield. Ripening of the fruit of peach trees grown in the greenhouse took place 30-40 days earlier that of field grown trees.
