In this article, the possibilities of water holding capacity in the leaves of triticale varieties were studied in the conditions of LFMC-70% and arid LFMC-50% of grassland-gray soils of Samarkand region, and the drought resistance characteristics of the varieties were studied. LFMC (Limited Field Moisture Capacity) was maintained at 70% under normal conditions and LFMC at 50% under dry conditions. According to the results of the experimental analysis, drought conditions had a significant and negative effect on the productivity of all studied genotypes. It was found that triticale cultivars "Odessiy" and "Tikhon" grown under LFMC-50% conditions in drought conditions meet water deficit less in all development phases and at all times of the day and are drought resistant compared to other cultivars. Analysis of the physiological and biochemical bases of adaptation in the selection of drought-resistant triticale varieties and the research conducted on the selection and obtaining of fertile varieties suitable for this region are described.
