The stress indicator widely expresses the impression of drought on barley genotypes throughout crown root initiation period, highlighting its worldwide effect production. So, it was urgent need to identify drought-resilient considering multi-trait genotype ideotype distance index (MGIDI). study, conducted evaluate grain output and genetic variations 50 using indicator. Under optimal conditions, IBON14 achieved highest yield 9.55 g/plant, while under stress, BD7194 produced 7.31 g/plant. Significant correlations, both positive negative (ranging from 0.66 1.00), were observed among tolerance indices yields. Using MGIDI index, selected as most drought-tolerant, followed by BD7188, IBON14, BD8579, IBON16, with a 5 % selection intensity. Factor study revealed diverse susceptibility indices, emphasizing robustness certain genotypes, all which grouped single factor. exhibited gain (%) between 39.9 113 %. Moreover, differential, calculated predicted values, varied 0.25 2.54, broad-sense heritability determined be ≥0.99. This emphasizes usefulness in selecting drought-tolerant proving resilient, exhibiting high stability gains.
