Evaluation of ten cherry rootstocks (’Bogdány’, Cerasus mahaleb ’Cemany’ (control), ’Egervár’, ’Érdi V’, ’Korponay’,’Magyar’, ’SM 11/4’, ’Vadcseresznye C. 2493’, ’GiSelA 6’, ’INRA SL 64’) combined with early ripening sweet cherrycultivars (‘Petrus℗ ’, ’Vera℗ ’, ’Carmen℗ ’) has been studied among non-irrigated conditions in Hungary. Trials wereset up at Research Station of Érd of Fruitculture Research Institute of National Agricultural Research and InnovationCentre. Aim of our study was to find suitable rootstock for novel bred Hungarian sweet cherry varieties. It can be statedafter seven years investigation that ‘Petrus’ was the most vigorous varieties, which is followed by ‘Vera’ and ‘Carmen’.The ‘GiSelA 6’ rootstock had low vigor among examined rootstocks and ‘INRA SL 64’ was the most vigorous one in ourtrial. ‘Petrus’ produced the biggest yield and the smallest fruit size among observed cherry varieties. Yield of ‘Carmen’grafted on ‘Érdi V’, ‘Egervár’, and ‘GiSelA 6’ was the highest but only ‘Érdi V’ had a positive effect on fruit sizebecause more than 40% of examined fruits were larger than 28,1 mm in diameter. ‘Vera’ yielded well on ‘Érdi V’ and‘Egervár’, the best fruit size was produced by ‘Érdi V’. On the basis of value –yield index, which was calculated byactual market price per fruit size category, ‘Carmen’ produced the highest income per tree on ‘Egervár’ and ‘GiSelA 6’and ‘Vera’ was the most valuable on other rootstocks.
