Some research results of the best pollinators selection for Prunus domestica cultivars

Abstract

The article presents the results of artificial hybridization of plum cultivars obtained inside of bilateral project between the Research Institute for Fruit Growing Pitesti (Romania) and the Institute for Fruit Growing Samokhvalovitchy (Belarus). The results of crossing in different climatic conditions are comparable to pollinator cultivars. Pollen germination in a laboratory facility is congruent with the results in the field. American cv. ‗Oneida‘ as a male component demonstrated the best crossing efficiency in both countries. The lowest level of fruit setting has been obtained using pollen of Canadian cv. ‗Vision‘ that does not permit to recommend it as either a male parent in hybridization or a pollinator in commercial orchards of cvs. ‗Avrora‘, ‗Experimental elegante‘ and ‗Tuleu timpuriu‘.
