The aim of the study is to select pepper genotypes with increased drought tolerance based on an economic assessment of productivity in conditions of water deficit. The experiments were conducted during 2018-2019 in glasshouse Venlo type in the MVCRI. Two variants of irrigation regime are applied: 100% irrigation norm and 50% irrigation norm according to the technology adopted for this production in eight pepper (Capsicum annuum L.) genotypes - lines № 1966, 1917, 1931, 1936, 1928, 1930, C41 and C45, which were cultivated as a substrate culture (PE bag 16 L) without heating. In assessing the economic indicators in greenhouse production of pepper in order to select drought-tolerant genotypes of pepper according to the summary indicator rate of return with the highest economic effect of drought achieved with reduced to 50% irrigation regime are distinguished lines № 1928, № 1966 and № 1931.
