Methodological and agrobiological substantiation of the expediency of the cultivation  apple (Malus domestica Borkh.) on the rootstock 54-118 in the Ukraines Northern regions / Chukhil S. M., Bublyk M.O., Pavluk V.V., Goncharuk J.D. // Sadivnytstvo (Horticulture). 2015. 69. P. 83-94. Refs.: 19. in Ukrainian.

The authors present the results of growing apple cultivars different concerning origin, vigour and ripening terms on the rootstock 54-118 in the period of the initial (the thirdseventh) and mass fruit bearing (the eigtheleventh years), the trees feeding area being 5 x 3 m. Cvs have been selected with the early maturity, the highest winter-hardiness and productivity. The arguments have been advanced about the expediency of growing those cultivars low and middle trees with the planting plan 3.54 x 1.5 m in order to achieve the annual yield above 2530 and in favourable years 5060 t/ha. Cvs have been determined that should not be grown on the above mentioned rootstock under the conditions of the intensive horticulture.

Key words: apple, cultivars,early ripening, yield, quality, productivity, resistance.
