In the conditions of the Republic of Belarus there were presented data on the results of the study of biometric parameters, indicators of productivity, the duration of tomato (Lycopersicon esculentum) hybrids fruits storage. Hybrids were obtained with the assistance of lines, carrying the long storage genes (NOR and RIN). According to the complex of agronomic traits, as the most promising, were marked five hybrid combinations: Line B-3-1-8 x Line 18/6, Line C-9464 x Line 18/6, Line - 322 x Line -18/6, Line - C-9464 x Line -19/0, Line -19/5 x Line - 19/6. Two of them are named Sapsan and Bubenchic are included in the State Register of released varieties and hybrids in 2011 and 2012, respectively. According to the results of biometric measurements of the best hybrid combinations it was found that the majority of samples relates to indeterminate group of plant with the height from 185 to 288 cm. A small number of brushes on the main stem (3,2-5,4 pcs.) was observed in the F1 hybrids Line - B-3-1-8 line x - 18/9, Line - N 4 x line - 19/6, at standard F1 Alexander, and the maximum number of brushes (from 9.1 pc. to 12.6 pc.) - the indeterminate hybrids.
