Development, implementation and promotion of new varieties corresponding to the consumers’ ever growing requirements continue to be a paramount task of breeders. Combination of variety and hybrid resistance to environmental stress factors with a high level oh productivity and production quality is a priority direction in the strategy of plant breeding at the agriculture adaptive intensification stage. The quality of tomato fruits depends, at a great extent, on the presence or absence of the green spot at the fruit base. A fruit is more attractive if it is ripening simultaneously and uniformly on the whole surface. This character is controlled by the u mutant gene. A comparative assessment of some tomato genotypes, according to a complex of useful characters was carried out to demonstrate the variability of agronomic characters and to specify the value of the tomato samples, carriers of the u gene, for breeding. The sample assessment was carried out based on the most valuable biological parameters (total yields and market yields, mean fruit weight, share of market fruits, vegetation period, resistance to drought and cold). The genotypes that combine earliness with high |
