The article offers short characteristic of Fj hybrid combinations and reveals type of inheritance by the folwiing characteristics: plant height, height of lower bean insertion, quantity of seeds per plant, quantity of seeds per plant, beans per plant, nodes and branches per plant, as well as determines proportion of dominations displaying high heterosis effect. Two superior hybrid populations, namely Amethyst/Miao-ian-Dou and Amethyst/Krasa Podillia, have been selected and are being used to scan for transgressive forms.

Scope of protection of plant variety rights granted to variety owner as provided for by Ukrainian legislation is established. Thus, basis is created to enable comparative analyzes of the national system of plant variety protection with analogous sys-terns existing in other countries, in particular, the protection available with utility patent.

Breeding of columnar type apple varieties has been carried out at VNIISPK since 1984. The possibility of grow-ing of columnar type apple varieties in the crown of winter hardy semi-dwarf rootstock 3-4-98 by S. N. Stepanov’s breeding is being studied in different density of planting in the orchard (3 x 1,0 m; 3 x 1,5; and 3 x 2,0 m). The inves tigation of winter hardiness, cropping power, fruit mar ketability and biochemical composition allowed releasing two varieties «Poesia» and «Priokskoye» for state trials.

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.

Stabilizing (centripetal) breeding produced donor of short stem characteristic for winter rye (Secale cereale L.) with height of plants ranging from cm 50 to 60. Distribution curve of plant's height remained symmetric with cummulation of frequencies at central classes (leptokurtic). For the first time, designation for new allele of short-stem gene HI-2HI-2 and donor name Gnome 2 was suggested. Gnome 2 was found to have direct genetic correlation of plant height with number of flowers in the ear, length of the ear, weight of 100 seeds from the plant, as well as reverse correlation with ear density and weight of kernels from the ear.

Diversity of sweet cheery varieties introduced on the in a steppe zone of the Crimea has been studied and 47 specimens perspective for breeding work on the following characteristics as blossom and ripening, yield capacity, fruit size, frost resistance, resistance to disease have been selected.

Complex assessment of varietal resources of the lettuce by means of identification of morphological descriptions and determination of indices of suitability for dissemination in Ukraine is considered. Contemporary classification by botanic and economic and consumption criteria of all the lettuce subspecies has been adapted.
