Investigaton in the plum orchard of NARIC Fruit and Ornamental Research Institute in Cegléd
Plum and apricot genebank collections of the Hungarian University of Agriculture and Life Sciences, Institute of Horticultural Science, Research Centre for Fruit Growing in Cegléd (Hungary) were established in the 1960s. The plum collection contains 385 accessions. Purpurovaja, Ruth Gerstetter and W.35 Myr. 368-2A are the earliest ripening cultivars harvested at the beginning of June. The cultivar collection is not virus free, but some cultivars (Albatros 2, Brassai and Pacifiq) remained virus free for a period of 15 years. Processed fruits of plums Opál, Čačanska Najbolja and Čačanska Rodna seemed most suitable for compote, while Zimmers Frühzwetche and Valjevka for juice. Plums Centenar, Gabrovska and Gras Ameliorat were found most appropriate for jam. Aim of our rootstock experiment is the investigation of effects of the commonly used Myrobalan C.162. rootstock for plum cultivars compared to eight, different rootstocks from abroad. Long-term results will be useful for nurseries and producers too in terms of extension of rootstock supplies. We planted Čačanska Lepotica, Haroma and Toptaste® Kulinaria(S) plum cultivars on Myrobalan C 162, GF 677, Marianna, Ishtara® (Ferciana), Myrobalan 29 C, Pumiselect®, Wangenheim, St. Julien A, Wavit® and Penta® rootstocks. Every combination was tested in 20 replications. First year results showed that every parameter of GF 677 was significantly higher than Myrobalan C.162 applied as control.
