The analysis of the structure of State Register of Plant Varieties Suitable for Dissemination in Ukraine is presented. The descriptions of new lupine's varieties important for economic use are given. The state of new varieties introduction in production and ways of improving of the soil fertility with a low humus content and the overcoming of crisis in the forage sphere are shown.

The genealogy of the separate sorts of mild winter of International Breeding Research Laboratory V. N. Remeslo Mironovka Institute of Wheat were analyzed. And sources of forming the sings, providing their high adaptability, were also found . it is shown that the main role in sort productivity, their stabilityto sickness and to unfavourable factors of environment played a starting material of west-european ecotype.

The cost-effectiveness of examination institutions activity of the State System on Plant Variety Protection was developed on the macro level. At the present stage there is an urgent necessity to provide with general methods to solve the tasks of the state scientific-technical program of plant variety examination.

The main principles of the forming of the scientifically based variety policy of Ukraine are described. A great role during the creating of varieties and hybrids with certain quantitative and qualitative characteristics belongs to the producers of the cereal and seed production, enterprises of the processing industry, firms, which supply their varieties to the world market.

Interrelation of plant height of winter wheat varieties with resistance to lodging and crops productivity has been investigated. It has been grounded expediency of corresponding agro-ecological conditions establishment, under which plant's height is formed within the limits of genetically caused optimum for each variety

Revealed main point of formation the matrix differences of lettuce seeds characteristics (Lactuca sativa L.), its correlation with other categories of heterogeneity. It’s been shown the ways of decreasing of the matrix differences of lettuce seeds characteristics with the aim to increase sowing quality of seeds.

The use of regression analysis for estimation of inbred lines is a breeding - oriented method, as it indicates scientifically grounded stages of the further breeding studying of these lines and a strategy of their use. Admissible levels of inbred depression of agriculturally valuable characters are limited in lines of the Verkhnyachka and Lgov geneplasms by two - three generations of self - pollinations, which testifies to the necessity "to keep" the characters of sufficient basis. Linearity of changes of values of the characters with the advancing of inbreeding shows the absence of epistasis or the weakness of their effects which makes suitable the use of an additive-dominant model for determining breeding-genetical value of inbred lines with the aim of their purposeful hybridization for obtaining genetically determined heterosis in F1.

The system of accelerated seed reproduction for new variety of winter wheat Krizhinka, and its application into production during years 1997-2000, are adduced in the article. Application of this system allowed in year 2000 to grow about 20 thousands metric centner of original seeds, and to increase the planted area at the time of including of the variety to State Register of Plant Varieties of Ukraine till 50 thousand he.
