Аннотация

It was done an assessment to the heat and water stress resistance of the selected tomato genotypes pollen under controlled conditions of multivariate complex that allowed revealing a differentiated response of gametophytes and on this basis to show the resistance differences between genotypes to these stress factors. A lot of interest in the selection represents the genotypes that displayed high resistance to gametophyte and sporophyte. Using a complex approach to the study of the heat resistance of tomato varieties allowed to make an assessment of the resistance of each genotype to the temperature factor and to identify the most promising genotypes for their using in further breeding work. 

Keywords: tomato, breeding, resistance, genotype, sporophyte, gametophyte.
