Abstract
The main aim of this study was to evaluate cultivar–rootstock combinations of almonds.
Experimental orchards were established in 2019 in Cegléd and Érd at the Hungarian University of Agriculture and Life Sciences, and in Tordas at the National Food Chain Safety Office.
Trees were planted at a distance of 6×4 m.
Four rootstocks (Cadaman®/Avimag, GF 677, Garnem®, and Prunus amygdalus) and four late-blooming cultivars (‘Tétényi rekord’, ‘Lauranne® Avijor’, ‘Supernova’, ‘Marokkói’). All combinations were planted in Cegléd and Tordas in 5-5 replications, and in Érd in 10 replications.
We investigated the height of trees, crown and trunk diameter, the density of flower buds, time of flowering, and the extent of spring frost damage.
Furthermore, in the following years we will examine fruit ripening time, fruit quantity, length, thickness, and weight of fruit and nuts. ‘Tétényi rekord’ began blooming, and then ‘Marokkói’ followed it at the end of March, while the other two cultivars bloomed rather in April.
Due to the cold nights during spring, frost damage may be up to 50% (e.g. ‘Tétényi rekord’ on Garnem® and GF 677 rootstocks or ‘Supernova’). ‘Lauranne® Avijor’ bloomed the latest, and it was measured the least frost damage, it was less than 10%. Flower buds per meter in the first year was outstanding in the case of ‘Tétényi rekord’ and ‘Lauranne® Avijor’. Cultivars blooming in April have less frost damage loss, and consequently, a larger yield can be expected.
The first results show that the cultivars ‘Lauranne® Avijor’ and ‘Supernova’ on GF 677 and P. amygdalus rootstocks are the first to bear fruit.
Next year it is planned that further cultivars and rootstock will be investigated such as ‘Rootpack® R’, ‘Rootpack® 40’ rootstocks, and ‘Penta’, ‘Makako’, ‘Vairo’ cultivars.
