ABSTRACT Turkey has quite a rich genetic diversity in various fruit and plant species. One of them is species in the Prunus genus. In addition, Turkey is the greatest or significant producer of many stone, nut and some fruit species. This study was conducted to determine the effects of intra-species hybridizations of some apricot (Prunus armeniaca L.) cultivars and inter-species hybridization of apricot cultivars with paternal parent plum (Prunus salicina L.) cultivars on fruit set and pomological properties of apricots. In both years of experiments, differences were observed in fruit set ratios of intra and inter-species hybrid combinations based on paternal parent cultivars. Among the apricot × plum inter-species hybrid combinations, the Black Amber plum cultivar was found to be prominent for the investigated parameters. Among the apricot × apricot intra-species hybrid combinations, Palstein group hybrids yielded greater values for the investigated parameters. Present findings may guide further researches to be conducted on intra and inter-species hybridizations of apricots and plums.

杏内种间杂交育种优良杂交种的评价

摘要 土耳其在各种水果和植物物种中具有相当丰富的遗传多样性。其中之一是李属的物种。此外，土耳其是许多核果、坚果和一些水果品种的最大或重要生产国。本研究旨在确定一些杏 (Prunus armeniaca L.) 品种的种内杂交以及杏品种与父本李 (Prunus salicina L.) 品种的种间杂交对杏坐果和果实特性的影响. 在这两年的实验中，基于父本栽培品种的种内和种间杂交组合的坐果率存在差异。在杏×李的种间杂交组合中，发现黑琥珀李品种在研究参数方面表现突出。在杏×杏种内杂种组合中，Palstein 组杂种的研究参数值更高。目前的研究结果可以指导进一步研究杏和李的种内和种间杂交。
