As climate changes are more and more evident, obtaining new elites in order to improve the assortment of apricots, with new varieties, having high agrobiological potential, requires a better selection of parental lines used for directed hybridization. In order to obtain hybrids with a high potential, the apricot varieties Elmar, De Valu, Augustin and Amiral were taken into consideration. The combinations used were the following: Elmar x De Valu, Elmar x Augustin, Admiral x Elmar. From the total of 2,500 hybridized flowers, a number of 150 viable kernels were obtained, resulting in a percentage of 6%, which means that there are factors that influence the hybridization process. High numbers of viable kernels were observed to be correlated with favorable weather conditions for the crop in that year. The research took place in the experimental fields of SCDP Constanta. They were planted in 2011, the planting scheme is 4/4 m, in an irrigated system. The trees are at full maturity, benefiting from an agricultural technique specific to the crop.
