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 is an alternative method for early determination of drought tolerant plants. The objective of this study was to perform in vitro selection of mungbean genotypes under water stress induced by polyethylene glycol (PEG) 6000. Seeds of 18 genotypes were germinated in Murashige and Skoog (MS) liquid medium supplemented with different concentrations of PEG 6000 (0, 8, 12 and 16%). Germination percentage, promptness index, root length tolerance index, seed vigor index, seedling length tolerance index, seedling fresh weight tolerance index and seedling dry weight tolerance index were measured. The results showed reduced germination and growth in all genotypes with increasing PEG concentrations. Various genotypes responded differentially at 16% PEG. Interestingly, K-851, EG-MG-13, VI000411 A-G, and CES 44 showed a higher germination percentage, root length, seedling length and seed fresh weight than other genotypes, demonstrating their drought tolerance potential. However, their water stress responses need to be confi rmed under greenhouse and/or fi eld conditions before they can be used as parents in breeding programs to improve drought tolerance.
期刊介绍：
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
