Preliminary results of 'Pertus℗', 'Vera℗' and 'Carmen℗' sweet cherry cultivars on Hungarian bred mahaleb rootstocks
Evaluation of ten cherry rootstocks (Bogdány, Egervár, Érdi V, INRA SL64, Korponay, Magyar, SM 11/4, Prunus avium C. 2493, GiSelA 6, control: Prunus mahaleb Cemany INRA SL 64 rootstocks) combined with early ripening sweet cherry cultivars ('Petrus℗', ʻVera℗', ʻCarmen℗') has been studied under non-irrigated conditions in Hungary. Aim of this study was to determine suitable rootstocks for novel bred Hungarian sweet cherry cultivars. After four years investigation that 'Petrus℗' was the most vigorous varieties, which is followed by 'Vera℗' and 'Carmen℗'. The GiSelA 6 rootstock had a low vigor among examined rootstocks and INRA SL 64 was the most vigorous one in the trial. 'Petrus℗' produced the biggest yield and the smallest fruit size among observed cherry cultivars. Yield of 'Carmen℗' grafted on Érdi V, Egervár, and GiSelA 6 was the highest, but only Érdi V had a positive effect on fruit size because 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 by actual market price per fruit size category, 'Carmen℗' produced the highest income tree-1 on Egervár and GiSelA 6 and 'Vera℗' was the most valuable on other rootstocks.
