In 1998-99 the effect of six rootstocks: P 14, M.26, P 60, P 2, M.9, and P22 - on some qualities of Jonagold and Melrose apples, after harvest and after cold storage was studied. The largest Jonagold fruits were obtained from trees on P 14 rootstock and those of Melrose on M.9. There were no significant differences owing to rootstock in fruit coloration. The maturity index indicated that Jonagold apples were more mature from trees P 60 or M.9 and Melrose from trees on P 22 or M.9. In general, P 14, M.26 and P 2 induced later ripening of apples. Jonagold fruits from trees on P 14 and Melrose fruits from trees on P 22 were firmer at harvest and retained higher firmness during storage. Dwarfing rootstock M.9, P 22 and P 2 promoted a higher content of soluble solids in Melrose fruits. Jonagold fruits from trees on P 14 and M.9 and Melrose fruits from trees on M.26 and P 60 showed the best storage capacity
