The method for identification adapted – morphological description of qualitative, quantitative and pseudo-qualitative characteristics of phenotype for cutting lettuce, as well as typical model of morpho-biological and economical parameters of new varieties of Romen lettuce for the purposes of official listing of varieties and rights herewith.

In this study, the mitogenomes of two Paxillus species were assembled, annotated and compared. The two mitogenomes of Paxillus involutus and P. rubicundulus comprised circular DNA molecules, with the size of 39,109 bp and 41,061 bp, respectively. Evolutionary analysis revealed that the nad4L gene had undergone strong positive selection in the two Paxillus species. In addition, 10.64 and 36.50% of the repetitive sequences were detected in the mitogenomes of P. involutus and P. rubicundulus, respectively, which might transfer between mitochondrial and nuclear genomes. Large-scale gene rearrangements and frequent intron gain/loss events were detected in 61 basidiomycete species, which revealed large variations in mitochondrial organization and size in Basidiomycota. In addition, the insertion sites of the basidiomycete introns were found to have a base preference. Phylogenetic analysis of the combined mitochondrial gene set gave identical and well-supported tree topologies, indicating that mitochondrial genes were reliable molecular markers for analyzing the phylogenetic relationships of Basidiomycota. This study is the first report on the mitogenomes of Paxillus, which will promote a better understanding of their contrasted ecological strategies, molecular evolution and phylogeny of these important ectomycorrhizal fungi and related basidiomycete species.

The above varietal structure of oilseeds in the State Register of plant varieties suitable for dissemination in Ukraine for years. In order to ensure stable population of oil and food, which include oil, and for the implementation of programs related to soil fertility, scientifically grounded recommended area of oilseeds in Ukraine for 2013–2015 years, ha.

The article presents the results of studies on the impact of time of sowing and seed rate linseed varieties on yield and seed quality in terms of the central Polessye.

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 best cabbage lettuce varieties for seedling and non seedling planting under the conditions of the open soil were defined. The potential productivity of the varieties under research in the conditions of the open soil were grounded from the scientific point of view. The influence of planting methods on plants productivity, produvtivity and quality of fresh lettuce heads was analyzed.

The article provides research results of the correlation analysis on Savoy Cabbage and Red Cabbage varieties and hybrids as recommended for cultivation in steppe of Ukraine, looking for increased production and diversification of vegetable crops, improvement of their quality. Direct and inverse correlations of quantitative features have been completed. The best standards are selected for Savoy Cabbage: Dafni F1 in early-ripening hybrid, Chifteyn Savoy variety in middle-ripening group, Vertyu 1340 in middle-late group, and there is Saga F1 RS hybrid late-ripening group. There is strong cross-correlation dependence registered for Red Cabbage was in Olena variety among a group middle-ripening group, Gako 741 variety in middle-ripening group, Kalibos, Dauerrot, in the group of middle-late varieties, and Milana, Langendeyker, Langendeyker red, Granat, Pozdnyaya Krasavisa, Maxilla and Autoro F1 and Fuego hybrids of F1 in late-ripening group.

The article proves that the genetic cluster analysis using of parents – offspring system at the period of 38 generations of directional intentional selection to short stem, the height of winter rye plants has been reduced less than 90 cm with simultaneously productivity integral components increasing. Directional selection on parent plants short stem has revealed pleiotropic effects to increasing averages of productivity yield capacity, spike length, flowers number, grains, and short stem and simultaneously its productivity reducing, plant and weight reducing of 100 direct descendants grains. Plant height donor of short stem Gnome 1 has been controlled prevailing by genetic factors and has been less influenced by environmental conditions. Selection by enlargement of elite plants grains has predetermined genetically increasing of the average height of families in the next generation without the concept selection requirements satisfaction. Therefore, the directed selections, by the structural analysis results, are annually held in two phases, first – to the expressed short stem and then among of them – to the high weight of 100 grains per plant and desirable productivity elements. A creative dominant short stem donor with stems up to 90 cm and a weight of 100 grains per plant more than 4.0 g has been made. A short stem spike shortness donor Dwarf 1possesses a significant reserve of common genetic mutation of quantitative characteristics, which can be used by direct and indirect selection. This population has been represented by its large amount, in order to enhance capabilities of directional selection plants short stem providing with the desired productivity components during the studying. Informative additive genetic cluster analysis is high. Plants productivity is considered to be extremely complicated selection characteristics, including many component constituents parts related genetically. One of these traits changing inevitably causes genetic changes in other breeding traits. The aim of the task should be set clearly and information flow should be methodically and genetically corrected used. Keywords: winter rye, the efficiency of selection, inheritance, short stem, Dwarf 1, pleiotropic effects, genotypic, additive correlation.
