The article discloses the meaning of botanical semantics, highlights practical appliance of binary scientific botanic nomenclature during plant varieties identification. It is the binary nomenclature of introduced cultivars that requires a scientific approach to structuring and developing the methodological and source learning database of botanical names in Ukrainian and Latin. According to the results of analytic monitoring, research aspects of differentiation of systematic units are shown, as well as certain rules and recommendations concerning theoretically sustained names of botanical taxa in Ukrainian and Latin. The scientific search for harmonization will enable to improve the practical appliance of methodological and linguistic and orthographic requirements and rules of spelling for botanical taxa names during the registration of rights on them. Spelling harmonization by Linnaeus semantic (in Latin) will facilitate a uniform approach to updating methodological and source studying database of binary names of the introduced cultivars of botanical taxa.

The article deals with analysis of scientific publications in the field of plant breeding, seed production and variety testing, archival documents and published government regulations. The comprehensive study lack according to creating history of a special protection system of plant variety rights is grounded, the necessary reproduction of stages of the State Protection of Plant Varieties forming is performed.

Molecular selection (MAS) makes the newest trend in breeding that has been progressively applied in many agricultural crops, including sugar beet. The article reviews papers on sugar beet MAL in Russia and overseas consi­ ering the methods applied and results obtained, das well as prospects for further development of this trend.

In the production of original, basic green pea seed it is critical to to single out (select) basic plants. The marked (selected) plants shall comply with their breeder’s description. Since seed breeding events are conducted with every new variety by various persons and in various agroecologic conditions, subjective factors, as well as environmental factors, may interfere with determining parameters of every characteristic considered there. As a consequence, identification and varietal characteristics and properties are subject to change and might not correspond to the breeder’s description; this, of course, affects the quality of variety. For the purpose of leveling the above factors, example of vegetable pea serves as a suggestion of a technique for exeminig parameters of variability of quantitative traits for specific population observing the rule of «golden section».

The article provides results of studying the output percentage of green stem cuttings of seven varieties of Highbush blueberry (Vaccinium corymbosum L.) subject to the dates of cutting preparation, type of shoot and its metamerism in agroecological conditions of the Rightbank Forest Steppe of Ukraine. It is found that green stem cuttings of Highbush blueberry varieties under review display low regenerative ability and are characterized with medium rooting ability. The optimal procuring and planting for rooting dates for the shoots fall within the stage of their intensive growth, which lasts from the first decade of June till the second decade of July. The level of regenerative capacity for the cuttings is determined by the type of cutting and its metamerism. Basal three-node cuttings have displayed essentially improved rooting ability as compared to the apical and medial cuttings.

The article mentions that 113 peach hybrid forms resistance to drought, to leaf curl infection Taphrina deformans Tul. and powdery mildew Sphaerotheca pannosa Lev. var. persicae Woronich have been obtained in the result of their studying. One of the most important agronomic sigh is a drought- resistance. Elite forms assessment on this indicator has been carried out in the most drought year during the last50 years. 23 forms with high drought-resistance have been selected. The leaves curl and false mildew are considered to be the most harmful fungal diseases reducing the plants peach vitality and leading to their lethality. Infection assessment has been carried out according to the average annual dates, and in epidemic (epiphytotic) year with a maximum disease revealing. As a result 14 hybrid forms infected by low leaves curl and 16 – by false mildew have been selected. According to the varieties characteristics complex 15 ones have been selected. Most varieties identified by their drought-resistance have belonged to the North Chinese eco-geographic group (59,1%), by a low leaves curl infection (Taphrina deformans Tul.) to the Iranian eco-geographic group (64,3%); by the false mildew (Sphaerotheca pannosa Lev.) to the Northern Chinese eco-geographic group (54,3%). The selected varieties perform the interest as sources of important mentioned economic valuated characteristics and they can be used in breeding.

The article highlights the results of studying the soft winter wheat response to the duration of enforced winter dormancy and the time of vegetation recommencing, their impact on growth, development and the survival of the crops. It is found that the impact of those factors in the conditions of central Forest-Steppe of Ukraine is essential, which is to be taken into consideration when scheduling the measures of spring and summer care over the cultivated crops, in particular, where the spring extra nutrition takes place, pesticides and growth regulators are applied, the spaced planting resowing or partial resowing issues are to be settled down. The ecological effect of spring vegetation recommencing dates does not expose annually, therefore it is not always possible to predict the plant development type, but it is possible, nevertheless, to influence the processes of growth, development and survival of plants throughout spring-summer period and the development of their production capacity by means of introducing the intense technologies, optimization of mineral nutrition and the use of plant growth regulators, protection from rogues, diseases, pests.

The article features summary of studying the resistance of rasberry promising varieties to main diseases (Didymella applanata Sacc., Gloeosporium venetum Speg. і Septoria rubi Sacc.) of stem expression type under the conditions of the Ukraine’s Northern Forest-Steppe. 8 summer rippeing varirties (‛Gusar’, ‛Kryepysh’, ‛Novokytaivs’ka’ (control), ‛Perseya’, ‛Saya’, ‛Tarusa’, ‛Phenomen’) were asessed, as well as the same number of that remontant (‛Babye lyeto 2’, ‛Heracles’, ‛Zolotyye kupola’, ‛Lyulin’, ‛Nyedosyagayemaya’, ‛Osinnya’ (control), ‛Osinny zorepad’, ‛Polana’). Weather conditions of the 2009-2011 vegetation periods were described. Favorable conditions were determined for the above raspberry diseases development. The studied varieties were divided into groups of resistance to the studied diseases. The resistance of the overwhelming majority of varieties was average to above average. The ‛Patricia’ and ‛Novokytaivs’ka’ (control) displayed low resistance against Dydimella and septoria spot, respectively. The varieties of ‛Kryepysh’, ‛Saya’, ‛Tarusa’, ‛Polana’, ‛Niedosyagayemaya’ and ‛Osinnya’ (control) have been found to display a complex resistance to Dydimella, anthracnose and septoria spot under conditions of the region researched.

The article performs the requirements to the preparation and Table characteristics content of the holding Test guidelines examination of new varieties to identify the difference, uniformity and stability. It is pointed that the identification of varieties is carried by the morphological characteristics description as presented in the table. Being standard these characteristics comply with ones requirements. An characteristics explanation with an asterisk (*) is given, their importance for the international harmonization of variety descriptions by States UPOV Members is indicated. The article presents an explanation of the grouping characteristics with documented revealing conditions. As it is commonly determined any characteristic begins with the plants or plants parts identification, which after a colon is followed by the body or its part nomination or by observed peculiarity. The requirements to the formulation of characteristics nomination are performed. It should be clear enough for understanding and without conditions determining. The degree of every characteristic nomination manifestation for its defining and making harmonizing descriptions is set. The corresponding numeric code, which facilitates the entry of data, drafting descriptions and their exchanging is given to each revealing degree. The morphological code configuration of variety phenotype is formed by the codes. It is emphasized that the features are divided into qualitative, quantitative and pseudo qualitative. The presentation order of the features in the table corresponds to the botanical or chronological order. It is noted that the Test guidelines should contain all the features suitable for holding examination at BOC and that there should not be any restrictions on their being included into Methods. Every feature can be used from a complete features list.

The article unveils the seed potential of fenugreek species to provide routine supply of methi leaf in the conditions of Ukrainian Forest-Steppe. The fenugreek species have have a wide range of morphological and economical characteristics variability that affect their seed production. A high productivity of dry seeds is inherent to fenugreek species at early spring sowing (10.04), as for this date the yield of dry seeds of blue fenugreek amounted to 0.4 t per ha, that of fenugreek hay – 2.0 t / ha, with mass of 1000 seeds, respectively, 0.71 and 9.7 gr. To obtain a spicery called «mushroom grass» the use of fenugreek hay is considered as a promising direction (Greek hay, Shambhala, hay fenugreek) along with scheduling the sowing for early spring (4.10) and late spring (25.04–15.05) , which would enable the development of greatest herbage volume and higher yield of mature seed (0.9–2.0 t / ha). Another prospective line of development is to use blue fenugreek (fenugreek blue) as a green manure and nectar bearing crop, with the sowing scheduled for spring (4.10) and late spring (25.04–15.05).
