The perspective hybrid forms between genus Prunus persica (L.) Batch and Prunus amygdalus Batsch, having high ornamental qualities and high resistance to Sphaerotheca pannosa (L v.) var. persicae Woronich., Taphrina deformans (Berk.) Tul., Clasterosporium carpophilum (L. v) Aderh., Monilia cinerea Bonord. have been obtained for using in breeding of peach and nectarine varieties and their rootstocks.

Genetic and statistical analyzes of ten quantitative characteristics inheritance of reciprocal populations F2 of three-hybrid crossing by plant height, leaf blade electroidy and absence of glaucosity on the plants of Winter Rye in three breeding institutions – Nosivskiy Variety Testing Station (VTS), Verhnianskiy VTS and Volynskiy Institute APV. Major portion of phenotype variation has been determined by environmental factors. Genotype variability of those characteristics is predetermined by effects of domination and epitasis, so the breeding aimed at acquirement of heterosis effect when ZKZ (ЗКЗ) and SKZ (СКЗ) are applied is expected to be promising.
