In Vitro Selection of Mungbean Genotypes for Drought Tolerance by Polyethylene Glycol Induced Water Defi cit

Drought stress is a major constraint affecting growth and yield of several economic crops including mungbean [Vigna radiata (L.) Wilczek]. In vitro selection for drought tolerance an alternative method early determination tolerant plants. The objective this study was to perform in genotypes under water induced by polyethylene glycol (PEG) 6000. Seeds 18 were germinated Murashige Skoog (MS) liquid medium supplemented with different concentrations PEG 6000 (0, 8, 12 16%). Germination percentage, promptness index, root length seed vigor seedling fresh weight index dry measured. results showed reduced germination all increasing concentrations. Various responded differentially at 16% PEG. Interestingly, K-851, EG-MG-13, VI000411 A-G, CES 44 higher length, than other genotypes, demonstrating their potential. However, responses need be confi rmed greenhouse and/or fi eld conditions before they can used as parents breeding programs improve tolerance.
