PRELIMINARY RESULTS ON GROWTH, YIELD AND FRUIT SIZE OF SOME NEW PRECOCIOUS SWEET CHERRY CULTIVARS ON HUNGARIAN BRED MAHALEB ROOTSTOCKS

Evaluation of ten dwarfing rootstocks (‘Bogdány’, Cerasus mahaleb ‘Cemany’, ‘Egervár’, ‘Érdi V’, ‘Korponay’, ‘Magyar’, ‘SM 11/4’, ‘Vadcseresznye C. 2493’, ‘GiSelA 6’, control: ‘INRA SL 64’ rootstock) combined with sweet cherry cultivars ‘Petrus^®’, ‘Vera^®’, ‘Carmen^®’ have been studied among non-irrigated conditions.
After four years data, it can be considered that ‘Petrus’ had small fruit size because diameter of examined fruits did not reach 24 to 26 mm in diameter.
This size is not the competitive fraction on the market.
Other examined sweet cherry varieties (‘Vera’ and ‘Carmen’) produced bigger fruit size compared to ‘Petrus’. Fruit size is important for sweet cherry because it establishes the market price.
To summarize results collected during the last four vegetation periods, the following groups can be considered on the basis of growth of rootstock/scion combinations: ‘SL 64’, ‘Cemany’, ‘Érdi V’, ‘SM 11/4’, and ‘Bodgány’ had strong vigor, ‘Korponay’ seedling rootstock, ‘Magyar’, and ‘Egervár’ showed medium vigor, while ‘GiSelA 6’ was semi dwarf. Cerasus avium ‘C. 2493’ has not been evaluated yet, because it was too early to claim its behavior. ‘Petrus’ on ‘Cemany’, ‘Egervár’, and ‘GiSelA 6’ produced the highest cumulated yield index, ‘Vera’ had the best cumulated yield on ‘C. 2493’ and ‘Korponay’ as well as ‘Carmen’ had good results on ‘Egervár’. Regarding Value-Yield Index, ‘Carmen’ reported the best performance due to its large fruit diameter.
