A detailed analysis of economic and biological characteristics, yield and grain quality of the studied varieties is given. The most adaptive varieties have been identified, which are characterized by high yield and grain quality and have a complex of economically valuable traits that are recommended for agricultural producers in the southern regions of the country.

Under laboratory conditions, studies of the effect of optical radiation on the growth energy, germination and average lengths of tomato sprouts and roots were carried out. The influence of the visible red, yellow and blue spectra on the seeds of the tomato variety «Malva» was checked.
