Sixteen plants were obtained after crossing Prunus domestica x Armeniaca dasycarpa. Twelve of them were identified as hybrids and were kept alive, the same as the variety Jibeck. Various degrees of domination of morphological traits of domestic prune were observed in the obtained hybrids. Black apricot traits were manifested weakly in seven hybrids, whereas in the other five hybrids as well as in the variety Jibeck we could observe the effect of doubling the set of genes which was brought into the zygote by unreduced microspores of the black apricot. Some important properties, such as resistance to abiotic and biotic environmental factors, growth inhibition, yielding capacity, earliness, and high quality of fruit, were combined in these hybrids. The obtained hybrids are very interesting from the viewpoint of selection and breeding of new varieties of domestic prune, tetraploid and hybrid varieties of black apricot, and apricots with some valuable traits of domestic prune.
