Abstract
Evaluation of ten cherry rootstocks (Bogdány, Cerasus mahaleb Cemany, Egervár, Érdi V, Korponay, Magyar, SM 11/4, P. avium C. 2493, GiSelA 6, control: INRA SL 64 rootstock) combined with early ripening sweet cherry cultivars (Petrus℗, Vera℗, Carmen℗) was studied in non-irrigated conditions in central Hungary.
The trial was set up at the Experimental Fields of NARIC Fruit Culture Research Institute at Research Station of Érd.
The aim of our study was to find suitable rootstock(s) for novel bred Hungarian sweet cherry cultivars.
It can be stated after eight years of investigation that Petrus℗ is the most vigorous cultivar, followed by Vera℗ and Carmen℗. GiSelA 6 rootstock showed the lowest vigor among examined rootstocks and INRA SL 64 was the most vigorous rootstock in the trial.
The trunk cross sectional area (TCSA) of Petrus℗ combinations grafted on INRA SL 64, SM11/4 and Bogdány was significantly bigger than on C. 2493, Egervár and GiSelA 6 rootstocks.
Other rootstocks such as Érdi V, Korponay, Magyar and Cemany indicated high to moderate high vigor for Petrus℗. The Vera℗/GiSelA 6 and Korponay combination had significantly smaller TCSA compared to most of Vera℗ combinations.
In the case of Carmen℗, rootstock INRA SL 64 and Cemany showed high vigor, Érdi V, C. 2493, Egervár, Korponay generated medium vigor and GiSelA 6 produced low vigor. Petrus℗ produced high yield and the smallest fruit size among observed cherry cultivars. C.2493 had lower cumulative yields than other rootstocks for Carmen℗ but only C.2493 had a positive effect on fruit size as more than 40% of examined fruits were larger than 28.1 mm in diameter.
There were no significant differences in cumulative yields of Vera℗ between rootstocks, but larger fruit size was produced by C. 2493, Erdi V and SM 11/4. On the basis of the value-yield index, which was calculated by actual market price per fruit size category, Vera℗ was the most valuable on Egervár, INRA SL 64, and Érdi V rootstocks.
