Purpose. Substantiating the selection of potato varieties for their ecological plasticity and stability to grow in Polissia. Methods. Field, laboratory, analitycal and statystical ones. Results. Impact of weather conditions during the growing season on the stability of potato varieties was estimated by indicators of yield, starch content and collection over the years by determining the average, standard deviation, minimum, maximum values and range of variation. ‘Memphis’, ‘Faluka’, ‘Arsenal’ and ‘Evolution’ were distinguished from the studied potato varieties by high genetic stability – their deviation from the average variance marked «minus» had values that were significantly less than zero. ‘Faktor’, ‘Flamenko’ and ‘Evora’ varieties are plastic (deviation is close to ±0), ‘Kolomba’, ‘Arizona’ and ‘Voliumiia’ ones – very plastic (deviation is most distant from zero). The studied varieties were distributed by homeostasis as follows: ‘Arizona’, ‘Colombo’, ‘Factor’ and ‘Memphis’ are the most valuable. Conclusions. ‘Evora’ potato variety can be considered intensive in terms of yield. ‘Evolution’ and ‘Flamenco’ varieties formed stable yields, during the years of study the difference between their maximum and minimum yields was the least – 8.2 and 9.3 tons per ha, respectively. Environmental assessment according to Eberhart and Russell indicates a high genetic stability of such potato varieties as ‘Arizona’, ‘Volyumiia’, ‘Kolombo’, ‘Evora’ and ‘Flamenko’. Conditions of Zhytomyr Oblast Plant Varieties Studying Centre are the most favorable among the studied regions to cultivate potato varieties.

Purpose. Identifying new scab-resistant apple varieties with high biological potential by the set of agronomic characters and the ability to realize it effectively in various soil and climatic conditions. Methods. Field, laboratory, comparison, generalization, statistical ones. Results. The author presents the results of study of 17 scab-resistant non-irrigated apple varieties on a semi-dwarf rootstock as to their adaptability to biotic and abio­tic stressors as well as their economic productivity. The studied varieties appeared to be winter-hardy, frost- and heat-resistant, but medium drought-tolerant ones. They are characterized by weak and moderate susceptibility to powdery mildew, high resistance to fruit rot and very low amounts of brown spot, except for Gold Rush variety. Such 10 year old varieties as ‘Edera’, Florina’, ‘Amulet’ and ‘Perlyna Kyieva’ and 8 year old ‘Afrodita’, ‘Vitos’, ‘Orlovskoie Polesie’ and ‘Topaz’ formed the highest productivity during the years of study. Due to the pollen quality and high interfertility, ‘Revena’ and ‘Gold Rush’ varieties were identified as universal pollinators for winter scab-resistant apple varieties. Conclusions. Such ecologically resistant winter varieties as ‘Topaz’, ‘Freedom’, ‘Edera’ and autumnal ‘Remo’, ‘Afrodita’, ‘Vitos’, ‘Amulet’ were recognized as promising for new intensive non-irrigated plantations in the Forest-Steppe zone of Ukraine. They can be the basis of new gardens occupying 25–30% of the area where ecologically safe fruits for various target purposes will be grown supplying demands of the population and processing industry.

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.

To analyse the modern classification and nomenclature of species of pome fruit crops which varieties are listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine, and improve terminological system of the Ukrainian names of both species and garden crops. Results. Fruit cultivars and most apple clonal rootstocks belong to Malus pumila, and ornamental cultivars belong to Malus gloriosa. The most common scientific name of the cultivated apple, especially among horticulturists, is Malus domestica, although according to the principle of priority the name Malus pumila should have the advantage. As far as Nomenclature Committee for Vascular Plants has rejected the proposal to conserve the name Malus domestica, Malus pumila is correct name for the cultivated apple. The use of synonymic name Malus domestica should be avoided in both scientific and scientific-popular papers for stability of nomenclature. Pear cultivars listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine are presented by Pyrus communis, and pear rootstocks – by Cydonia oblonga. Fruit cultivars of the latter belong to separate fruit crop named quince. An apple-quince hybrid was registered as universal clonal rootstock for pome fruit crops. The State Register of Plants Varieties Suitable for Dissemination in Ukraine also contains nonconventional fruit crops such as Chaenomeles and hawthorn that consist of some species and nothospecies. Conclusions. In scientific publications one should stop the use of synonymic name Malus domestica in favour of the correct name for cultivated apple Malus pumila. Apple, pears and Chaenomeles cultivars listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine have a complex multispecies origin whereas quince, hawthorn and pear roostock cultivars systematically are monospecies. A universal roootstock of pome fruit crops is Cydolus, or apple-quince, that resulted from interspecies hybridization between quince and apple. Refusal Refuse to use obsolete names of fruit plants species will promote harmonization of professional language.

Purpose. Considering ways to solve issues related to soil cover study at the institutions for plant varieties examination. Methods.Fieldandanalytical ones. Results. Issues are identified that arise during soil sampling at institutions for plant varieties examination within the state system of plant varieties protection. The author considered in detail the current soil sampling techniques for agrochemical tes­ting for humus, nitrogen (compounds to be easily hydrolyzed), mobile P2O5, exchangeable K2O, hydrolytic acidity and others. Attention was paid to violation of methodological requirements concerning the time of soil sampling and number of samples for agrochemical testing at the experimental field, to the lack of devices for meteorological observation and appliances for soil and leaf diagnostics. The article also touches upon the issues associated with the study of soil cover at fields with scientifically-based crop rotation that belong to institutions for plant varieties examination within the state system of plant varieties protection. Conclusions. It should be necessary to follow recommended practice when sampling at elementary sites for agrochemical testing and performing all operations in accordance with crop cultivation flowcharts. General recommendations for agrochemical testing of fields in case of conventional crop rotations in farms are not suitable for fields with scientifically-based crop rotations at institutions for plant varieties examination.
