Abstract
Ten cherry rootstocks (‘Bogdány’, ‘Egervár’, ‘Érdi V, Korponay, Magyar, SM 11/4, C. 2493, GiSelA 6, INRA SL 64 and Cemany as a control) combined with three early-ripening sweet cherry cultivars (Petrus®, Vera® and Carmen®) have been evaluated under non-irrigated conditions at Experimental Fields of NARIC Fruit Culture Research Institute (central Hungary). 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℗ was the most vigorous cultivar, followed by Vera® and Carmen®. The GiSelA 6 rootstock had the lowest vigor among examined rootstocks and INRA SL 64 was the most vigorous.
Trunk cross-sectional area (TCSA) of Petrus® grafted on SM11/4 and Bogdány was significantly higher than on C. 2493, Egervár and GiSelA 6. Other rootstocks such as Érdi V, Korponay, Magyar and Cemany indicated high to moderate high vigor for Petrus®. GiSelA 6/Vera® combination had significantly smaller TCSA compared to combinations of Vera with other rootstocks.
Vigor for Carmen® with Cemany was high; with Érdi V, C. 2493, Egervár, and Korponay it was medium; and with GiSelA 6 it was low. Petrus® produced the biggest yield and the smallest fruit size.
Yield of Carmen® on Érdi V, Egervár, and GiSelA 6 was the highest, but only Érdi V had a positive effect on fruit size with more than 40% of fruits larger than 28,1 mm in diameter. Vera® yielded well on Érdi V and Egervár, and the best fruit size was produced on 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 most valuable on Egervár, INRA SL 64, and Érdi V rootstocks.
