Abstract

The experiment was established at the Fruit Experimental Station Samotwór near Wrocław in 1993–2002. The aim of this study was to estimate the production value of 22 plum cultivars grafted on ‘Myrobalan’ seedlings (Prunus divaricata). Results of the study proved that ‘aanska Najbolja’ and ‘Magna Glauca’ cultivars were the most vigorous, while ‘Bluefre’ and ‘Auerbacher’ were characterised by the weakest growth. ‘Bluefre’, ’President’, ‘Ontario’ and ‘Auerbacher’ cvs. were the most productive. Mean fruit weight was significantly dependent on the cultivar, too. Among the tested cultivar, the biggest fruit was obtained from ‘President’, ‘Valor’, ‘Bluefre’ and ‘Ontario’ trees. The most sensitive to plum pox virus (symptoms on fruit and leaves) appeared ‘Węgierka Zwykła’, ’Węgierka Zimmera’, ‘Ortenauer’ and ‘Magna Glauca’.
