Almond, peach and nectarine are among the most wide-spread fruit-bearing crops in the world. The almond is characterized with high taste qualities of seeds, for peach and nectarine juicy and taste pericarp is a typical feature. Combination of these crops properties is possible applying method of distant hybridization. The researches were being conducted in 2004-2016 in Nikita Botanical Gardens, Russian Federation. The following species were chosen for breeding work: Prunus amygdalus Batsch., Prunus persica (L.) Bastch., Prunus persica (L.) Bastch. var. nucipersica (Suckow) Schneid., Prunus mira Koehne., Prunus davidiana (Carr.) Franch. It was revealed among new hybrids there are genotypes with late blossoming terms, dwarf plant size and male sterility. Hybrids with semidouble flower are classified here as well. A high variability of fruit ripening terms is typical for the hybrids: from the beginning of August to the end of September. Taste quality and fruit weight of these hybrids are mainly worse than control nectarine cultivar has. Good taste quality of these hybrids, close to Stark Sunglo parameter was fixed only for some genotypes by F4-F5. Saturated crossing with nectarine let increase fruit weight up to level of the control cultivar by F4-F5 as well.
