Influence of varietal characteristics and growth factors on the quality of Natsional’na and Polis’ka 90 winter wheat varieties was studded. Grain of Polis’ka 90 variety was distinguished by considerable variability of grades, however, the grain of Natsional’na variety was exposed to greater number of growth factors. Grain unit index influenced the grain quality grade of Natsional’na 90 determination, gluten quality and protein and fiber content indices influenced that of Polis’ka 90. It was established that the grain of Polis’ka variety in most of the cases had higher grades of quality than Natsional’na variety. The highest grades of quality were registered for the seed harvested after perennial grasses, namely 2d and 3d grades of Natsional’na variety and the 1t and the 2d for Polis’ka 90 variety. Greater grades of quality were registered for the seed grown according to intensive and ecological farming systems (generally, grades 1 to 3), while the lower grades were inherent to biological system (generally, grades 3 to 5).

The article deals with priority directions of vegetable and melon plants selection. The wide varieties of alien genetic information transferring methods during the transgenic plants creation of vegetable and melon species are grounded. The essence of the new hybrids identification method as genetic engineering products: kind of cabbage, tomatoes, carrots, zucchini, lettuce seed, pea Pisum sativum), common bean, eggplant and capsicum is revealed. The transgenosis main directions of botanical taxa varieties of vegetable and melon plants on condition of the international and national practice holding are proved. The international practice of the state approbation and registration of genetically engineered structures in biological objects (plant varieties) and in their processed products are studied. A monitoring about food and pharmaceutical substances based on genetically modified varieties and hybrids structures of vegetable and melon plants have been held.

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.

The article reflects economical value and origin of maize as an important energy crop. It specifies volumes of bioethanol production worldwide, as well as analyzes legal provisions for the development of alternative power engineering, advantages and shortcomings of bioenergy is general.

Те article reflects summary of hybridization and assessment of genetic value of pollen-sterile maternal lines of various origin and tetraploid pollinators produced by Bila Tserkva selection. High differential potential of pollinator-testers has been established. Best components exhibiting high combinative features have been detected, which served as a baseline for establishing MS (male sterile) hybrids of sugar beets.

The paper studies level of economically valuable characteristics of tetraploid lines of sugar beet developed at Bila Tserkva research and breeding station. Collection is established on that basis of highyield and high-sugar lines, hybridization with which has produced triploid MS hybrids displaying veracious excess of group standard for yielded sugar by 15...28%.

Methodology for detecting correspondence of soft wheat to the criteria of distinctness, uniformity and stability based on researching peculiarities of morphological characteristics expression, has been scrutinized. It is established that, in the complex of many of those characteristics characterizing variety phenotype, for its identification only those characteristics are used that are exposed to lesser degree to the influence of environmental conditions.

The article provides results of efficiency of double screening by quantity of normally developed germs affected of unfavorable abiotic factors, namely decreased temperatures of seeds sprouting and embryogenesis at extremes (heat, shortage of water).

The article describes Agro-ecological features of winter triticale variety Vivate Nosivskyi developed by means of individual selection based on hybrid combination ([Avgusto x NE 312] x К 9844) at the Examination Facility of Nosivska Breeding and Testing Station ofChernigivIAPPIAAN and selected by quantitative (grain productivity, quantity and weight of grains per ear, cup weight of grain, 1000 kernels weight), qualitative (protein contain, «raw» gluten) parameters of grain yield, by adaptability to a range of causative agents, abnormal events in winter-spring and summer, lodging. It shows that bio-agents of microbe preparations Azospirillum brasilense и Achromobacter album 1122 on initial stages of development of winter triticale variety Vivate Nosivskyi plants enhance nitrogen and phosphor nutrition as reflected in raw and dry weight of plants increased by 1,5 to 2,5 times, area of leaf surface - 2 to 2,4 times, grain yield -1,1-1,3 times.

Assessment is made for heat-resistance of 10 promising domestic and foreign apple varieties, as well as for their drought- resistance (leaf tissue water content, water holding capacity and turgorescence); also, impact of weather conditions on implementation of its drought and heat resistance by the research subject is determined. The article highlights the best in Ukraine’s Forest-Steppe environment by the above economical and biological properties apple varieties.
