N2 - One of the most important factors affecting the financial outcome of commercial fruit growing is the success of pollination and fertilization, which in turn are dependent on weather conditions, activity of pollinators and the compatibility and overlap in flowering of the cultivars. Before introducing new cultivars, it is obviously important to know the compatibility and flowering characteristics of the genotypes. In order to find out these attributes of seven new and four established plum cultivars, pollen germination tests, hand pollinations and flowering phenology observations were carried out. ‘Prosser 84’ had 70% pollen germination. ‘Opal’ had just 3%, probably due to aged pollen. ‘Anna Späth’ flowered over a short period (13 days) and ‘1468’ and ‘DCA BO 46’ over long (19 days) periods; the overlap of all cultivars was relatively good. With ‘1468’, ‘Victory’, ‘Anna Späth’ and ‘Prosser 84’ flowering intensity varied between years, ‘Jubileum’, ‘V70032’, ‘Tita’ and ‘DCA BO 46’ flowered regularly, the others were intermediate. ‘1468’ and ‘WJ 65’ flowered early, ‘Prosser 84’ and ‘DCA BO 46’ late and the rest fell in between. ‘Victoria’ proved to be self-fertile, ‘Jubileum’, ‘V70032’ and ‘1468’ semi self-fertile. Fruit set percentages after June drop of all crosses were rather low; varying between 0 and 28%. With ‘Tita’, fruit drop occurred approximately two weeks later than with the other cultivars
