Prebreeding research on Malus domestica Borkh. specimens was conducted to broaden the genetic diversity of cross breeding components for faster creation of cultivars of adaptive and technological orientation. 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.
