Results of four-years assessment of approximately 90 winter wheat varieties at post- registration research on the background of crops chemical protection and in its absence at Biloczerkivska DSDS (forest- steppe zone) and Borodianska DSDS (subforest zone) are represented in this article. Methods of their immunological assessment and determination of potential productivity have been developed too. Authors are recommending to conduct immunological assessment of varieties on their natural background of diseases development and assess potential productivity in conditions of plants chemical protection as this is the element of crop growing technology.

Crop capacity and productivity elements of winter wheat domestic sorts have been investigated. Valuable sources on the basis of given characteristics for getting selective material of high quality have been singled out. Correlation relations between crop capacity and productivity elements of winter wheat sorts have been established.

Purpose. Reviewing the literature on modern technologies of genetic modification of crop genomes. Results. The current state of genetically modified plants creation is analyzed. The information on cis-, intra- and subgenic plants and their comparison with transgenic crops is given. Examples of cis- and intragenesis application for improving characteristics of crops are provided. Such state-of-the-art technology of crop genome modification as genome editing is considered. Conclusions. Technologies for producing cis-, intra-, subgenic plants are rapidly developing and resulting in crops of the 21st century that can solve the problem of food provision for a constantly growing world population with the least contrary to the public interest.

The article presents summary of the research of inheritance issues, as well as permanency and polylithism of soft wheat plants, and utilization of the above trait for identification of genotypes in the course of DUS examination of varieties. Relation of height of plants to their resistance to lodging and crops productivity has been studied. Expediency has been grounded for setting respective agro- ecological conditions enabling the plant height to fall within the limits of genetically conditioned optimum for every variety.

Investigational development of modern treater seed of agricultural cultures status. The analysis of efficiency of work control the system modem treater seed is conducted. The ground of creation of cont rol the system by the concerted serve working liquid (liquid poison) and seed is conducted in the working area of treate.
