Abstract
Drought is a serious concern in agriculture, affecting yields all around the world, and is becoming a major source of food scarcity in many nations. The genetic potential of twelve different sorghum genotypes for drought tolerance and germination was evaluated at Sardarkrushinagar Dantiwada Agricultural University in 2018. Water stress was created by employing non-ionic PEG-6000 to lower water potential. The experiment was set up using a complete randomized design with three replications. The experiment included twelve distinct sorghum genotypes with four different PEG-6000 treatments ((S1) 0%, (S2) 5%, (S3) 10%, and (S4) 15% treatment). Our goal in this study was to evaluate 12 sorghum genotypes based on physiological responses as well as drought tolerance. Germination percentage, shoot length, root length, shot dry weight, root dry weight, seedling vigour index, and Root: Shoot ratio were all traits evaluated. Significant differences were observed among the treatments in all 12 sorghum genotypes and genotypeDS-183 was more tolerant to simulated drought stress with PEG-6000 than other sorghum genotypes.
