The article shows development of the variety testing network of the official system of right protection for plant varieties. The article defines on the art-of-the-day level the main problems and relevant solutions, and points out the importance of examination institutions of the official system of right protection for plant varieties for solving the food provision problem of the state.

The article represents results of researches of 20082010 years and evaluation of the new registered and promising varieties and hybrids winter rape (seed) by their genetic potential productivity and adaptability. Changeability varieties according to high-yielding properties and elements of productivity depending with adaptability to the environmental conditions of areas of Forest, Forest-steppe and Steppe of Ukraine. There are discussed the prospects of the trends.

The estimation of drought hardiness of sea buckthorn varieties of different environmental and geographical origin was made in the field and laboratory conditions. In late August the drought hardiness was estimated according to leaf injures and abscission in the field conditions. In the laboratory conditions were determined the main characteristics of water regime: tissue water saturation, water deficit, leaf water retaining ability. As a consequence, the studied varieties were divided into groups with different drought hardiness degree.

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.

The article explains the aim and objectives of parental components of maize hybrids identification in the course of soil varietal control. Scientific background has been provided to methodological aspects of comparative evaluation of morphological characteristics on control plots for the purpose of establishing authenticity of maize hybrids circulated at the market.

The article displays economical value, as well as directions of use for valuable protein crop, soybean, as well as growth rate of its production during recent years in the world scale and in our country, establishment of its varietal resources in Ukraine. Complete description for new soybean varieties listed in the State Register of Plant Varieties Suitable for Dissemination in Ukraine is provided for those having Official Description.

Capitalistic relations were contributing to origination of research breeding during the second half of ХІХ Century. Breeding and seed companied were starting to emerge in Europe in the middle of ХІХ Century. Most famous among them were Velmoren, Depre, Turner (France), Rabbetge and Gizeke (Kleinvantsleben), Dippe und Shriber (Germany) and other.

The article reflects the progress of genetic decrease of Rye F 3k- 10029/ Saratovske (Саратовське) 4 height by means of the shortest stem plants selection during the period from 1974 to 2010. 37 years selection of the shortest- stern genotypes decreased the plants height from 119.33 cm to 22.57cm. Targeted selection into minus direction decreased the plants height in 5,29 times on the background of the dominant HI expression. In average, the height of plants in the course of 27 breeding cycles were decreasing by 2.69 cm, but that was not going gradually. A new donor Gnom 3 had been created for ultra short-stem trait of the Winter Rye, with the marking of alleles HI-3HI-3. Relative influence on the minus selection efficiency has been established by height of plants for the selection differential (38%) and coefficient of inheritance in narrow sense (14,56%). Realized efficiency of selection in decrease of winter rye height in 72,08% of cases corresponded to predicted hit ration of the breeding. Analyzes of genetic and statistical parameters and correlation clusters of 11 utilitarian average characteristics of ultra short- stem rye Gnom 3 for the period of 1974 to 2010 has been performed.

The article researched genetic potential, morpho-biological characteristics and features of new varieties of winter wheat varieties of semi-dwarf and short-stem types. It was established that new generation of such varieties displayed improved architectonic of plants, as well as a complex of morphological and economical value chararacteristics and features, combined high genetic potential of productivity with good adopting features, and short stem with high resistance to drowning, and generated higher crop capacity compared to conventional mid-ripening varieties.
