The invention refers to agriculture, particularly to methods for selecting drought-resistant tomato genotypes.The method, according to the invention, includes collection of completely tripped flowers of each genotype, separation of pollen from anthers, division of pollen into two parts, maintenance during 6 hours: of one part of control pollen at the temperature of 27?C, of the other sample pollen at the temperature of 45?C, separated cultivation of the control and sample pollen on a nutrient medium, modeling the drought conditions, determination of control and sample pollen viability by the ratio between the number of germinated pollen grains and the total number of analyzed grains, expressed in percents, calculation of indexes of pollen resistance to drought by the ratio of sample pollen viability about the control one, expressed in percents, being selected genotypes having higher drought resistance indexes.
