One of the main problems of modern vegetable growing is the creation of varieties with complex valuable traits, adapted to growing conditions and economic efficiency. The forms containing the β (carotene) genes and r (yellow flesh), which play an important role in the diet of allergenic people, especially children, are of particular importance for improving red tomatoes. To demonstrate the variability of agronomic characters and to elucidate the value of tomato genotypes carrying β (carotene), r (yellow pulp) genes, a comparative assessment of tomato genotypes was made taking into account a set of useful traits. The evaluation of genotypes was carried out based on the most valuable biological parameters (period of vegetation, number of fruits and productivity per plant, fruit mass, thickness of pericarp, heat resistance). Genotypes combining characters of early ripeness with high productivity were identified in the tomato collection. Analysis of tomato genotypes for heat resistance made it possible to reveal highly resistant genotypes that are of interest as an initial material for breeding.
