Plum genetic resources were studied in the period 2004-2012. The fruiting type was established and the cultivars were divided into three groups. The major characteristics like fruit and stone weight, dry matter and acid content, fertility, resistance to PPV, frost and drought hardiness were identified and donors were selected for the breeding aims. 43315 flowers were pollinated in 61 parental combinations in the frames of the breeding programme and 459 hybrid plants were obtained and have been studied. Elites of valuable economic and biological characteristics were selected.
