Abstract The article deals with the advantages of tomato crop, highlights the significance of scientifically based selection of varieties and hybrids in cultivation technology, presents the analysis of the latest research and publications on the productivity of modern genotypes from various selection companies in different enterprises in Ukraine. The article gives the results of experimental studies conducted with tomato hybrids of middle (Leader F1, Asterix F1) and late (SHD 277 F1) ripening under conditions of drip irrigation on southern black soils of PRAE agricultural company «Rodnichok», Snigurivskiy district, Mykolayiv region in 2011-2013. In the years of research the minimum level of yielding capacity was formed by the tomato hybrid of middle ripening Asterix F1. The tomato hybrid Leader F1 was characterized by higher yields. The article provides a comparative assessment of the yielding data of the above mentioned hybrids. Due to a longer growing season the highest yield of tomato fruit was formed by the hybrid SHD 277 F1. The maximum difference between the productivity level of all tomato hybrids cultivated in the experiment was observed in 2013, which was connected with the most favorable weather conditions prevailing during the growing season in comparison with all the years of research. The late ripening hybrid SHD 277 F1 had the highest content of dry matter in tomato fruit in all the years of research. The middle ripening hybrids had much less quality parameter. In the group of middle ripening hybrids we observed a clear regularity: regardless of the year of growing the tomato hybrid Asterix F1 was characterized by somewhat higher content of dry matter in tomato fruit. However, due to the higher yielding capacity the middle ripening hybrid Leader F1 provided a larger amount of dry matter per hectare of tomato crops. It is proved that under conditions of drip irrigation on the black soils in southern Ukraine the middle ripening tomato hybrid Leader F1 has the highest yielding capacity (on average 93.7 t/ha during 3 years), and this hybrid provides the amount of dry matter of 4.6 t per hectare. The late ripening tomato hybrid SHD 277 F1 is able to provide the yielding capacity of 112.6 t per ha (an average parameter during the three years of research). The maximum capacity is observed in the years of favorable weather conditions (2013 - 128.5 t/ha).
