It was studied the impact of mineral fertilizers on productivity and grain quality of wheat durum spring. Glassiness of grain, protein and gluten contain increase along with increase of doses of nitrogenous fertilizer. Maximum grain productivity was achieved by mineral fertilizers in combination on autumn fallow N60P60K60. after pea - N90P60K60

Firstly in Ukraine as the result of resiprocal interbreedings of autotetraploid (2n=4x=32) / diploid (2n=2x=16) and diploid (2n=2x=16) / autotetraploid (2n=4x=32) four sintetic triploid (2n=3x=24) hybrid forms (611-91, 13-93, 14-93, 18-93) have been obtained. Spontaneous triploid nectarinum 166-80 has been shared out from diploid hybrid seedlings population. Tetraploid and triploid nectarinum forms are valuable sources for directoinal selection and making hybrids with the complex of new signs, which are difficult or impossible to receive on diploid level.

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 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.

State of national recourses of Sown Lettuce is considered, as well as way of their formation. Methodological aspects of biological potential utilization of Sawn Salad (leaf, head, Rome, stem) are displayed to widen their assortment. Dependence of marginal potentially possible yield of the Sown Lettuce varieties on influence of the environmental causes has been established.

The infection by phytoviruses and the productivity formation in the new varieties of winter bread wheat in the different years with virus damage were investigated. There were identified the varieties being more tolerant to the observed diseases, among these - the samples with different constituents of tolerance, which could be used in the breeding programs.

Possibility of heterosis effect approbation by using synthetic varieties of winter rye was discussed. Heterosis level of first five generation of rye synthetics did not decrease. Considerable yield decrease of winter rye grain took place in later generations. Concept of synthetic varieties of winter wheat creation in Ukraine is prospective, though it requires scientific, economical and legal improvement.

History of Winter Wheat breeding rise at the South of Ukraine since the end of XIX century till the beginning of October Revolution by the example of Breeding department at Odessa Research Field is represented. Odessa Research Field was established in 1894 to study the agrotechnics of agricultural crops, in particular, Winter Wheat. The Breeding department at Odessa Research Field was established in 8th of March, 1912, and headed by Private- Docent of Novorossiysk University, A.O. Sapegin. The main procedure applied in breeding was individual multifold selection of elite ears from the existing local blends and artificial crossing of lines selected to the purpose of improving economically valuable characteristics and identifying the inheritance. Five years of breeding (1912-1917 pp.) resulted in creation of three Winter Wheat varieties: Kooperatorka (0194), Zemka (0158) and Stepniachka(0119). In 1918, the Council of People’s Commissars of USSR has parted the Breeding department of Odessa Research Field to independent Odessa agricultural breeding station recognizing development of plant varieties by the Department.
