Genealogical analysis has practical value in the study of the apple trees gene pool for accelerated development of cultivars with desired properties. Genealogical analysis of 55 apple cultivars from the gene pool of branch of the Department of Horticulture of Kuban State Agrarian University — Krymsk Experimental breeding station (Krymsk), complex donors were selected by traits of immunity to scab and high quality of fruits — ‘Gold Rush’, ‘Pristine’, ‘Enterprise’. Cultivar ‘Golden Delicious’ was selected as a “hidden” donor by the trait of medium (autumn) ripening time. Key words: apple, genealogy, new source material, valuable traits donors, cultivation technology.
