ResumeWater deficit is one of the significant environmental factors limiting plant production. This stress occurs during drought period. The aim of this study was to select gamma irradiationinduced drought tolerant mutant drought lines during vegetative stage. Seeds of the reference cultivar were gamma irradiated using the gamma irradiated facility at the IAEA to induce genetic variation. Four selected lines based on their high biomass (L2, L17, L18 and L23) and the reference cultivar (L0) were grown under four irrigation frequencies: 2, 4, 8 and 12 days with 200 ml as standard water regime for 24 days after transplanting. Completely randomized block design with 3 repetitions was applied. Data related to Relative Plant Height Growth, Relative Leaf Number Growth, Relative Shoot Fresh Mass Growth and Relative Root Length Growth were determined. The results indicated a significant effect of water deficit on all considered parameters by limiting the growth. Reduction observed were less accentuated in lines L2. Line L2 showed a significant difference for root growth indicating the adaptability of drought. Based on drought tolerant index, L2 was the most tolerant. At this stage, lines L2 appeared to be the most promising for the creation of new drought-tolerant amaranth varieties.
