Abstract:
To determine the capability of 9 sour cherry cultivars to set fruit, two factorial experiments were carried out during 2008 and 2009. Flowers of each cultivar were isolated and pollinated with the pollen of donor cultivars. Arc-sinus transformation was carried out on the final fruit set percentage data. In the case of open pollination, average fruit set of all cultivars was 11%, compared with artificial self-pollination (9%) and natural self-pollination (2%). ‘Debreceni bőtermő’ was the best pollen donor for other examined cultivars, with more than 90% overlap of flowering time and 37% fruit set in 2008. The results of reciprocal cross-pollination will be discussed.
