Assumption is made that identification of valuable genotypes is possible in specific stability points of phase-parametric systems, that is, when the effect of dynamism acquires gradient and discrete anisotropic composition by way of converting the phenotype variability in the temporal and parametric and characteristic specific vector-spaced system. Devices have been suggested (electronic board for the characteristics spectral expression, 3D configuration of a characteristic variation series) for displaying the location sample parametric pool in the general statistic range of quantitative characteristics. A characteristic has been detected (number of seeds in a pod) that carry the traits inherent in pseudo-qualitative and oligogenic characteristic. According to findings of the study, characteristics are identified that conform to various directions of economical use

For the resistance to a soil drought in the early stages of seed germination the key role plays the primary root system: an activity of seed germination, the number of seminal roots and their length, dry weight of roots and coleoptile length and also the degree of cold resistance at the seedling stage. The stages and methods of the creation of six-row medium-grown barley varieties Vakula and Helios and semi-dwarf varieties Ros and Halychanyn are described.

It is determined that crop cultivation systems (continuous culture and its interruption by crop rotation links with different fertilizer backgrounds) influence the productivity and economic efficiency of tomato and cucumber cultivation under rainfed conditions in Right-Bank of Forest-Steppe zone in Ukraine. Reported calculations show the increased level of profitability of the continuous crop growing in case of interruption by annual crop rotation link against the background of mineral nutrition, but additional organic fertilizers allow to get more profit per unit area.

Under investigation inflluence period of sowing and presowing processing on productionity seeds of dill.

Scientifically validated items of growing technology disclosed for cos lettuce marketable products in the conditions of Forest-Steppe of Ukraine. Impact of environmental factors onto growth and development of Lactuca sativa var. longifolia L. plants. Sowing terms established for the seed of cos lettuce at field-seeded growing. Development parameters are quoted for plant productivity indices and marketable product indices for cos lettuce of national and foreign breeding. According to VCU characteristics a typical model has been designed for the cos lettuce indices of suitability for dissemination in Ukraine.
