Abstract
Background: Bambara groundnut has the ability to drought tolerance and has high nutritional value and is one than Legume crops untapped, which need attention. Therefore in this research, it will look at the relationship between osmotic stress caused by a concentration of PEG and drought tolerance to get some genotypes has ability drought tolerance.Methods: The experiment was conducted in the Tissue culture Laboratory, Department of Agronomy, Faculty of Agriculture, the University of Brawijaya, Malang, Indonesia in January-March 2019. The objective of the experiment was an evaluation of some morphological criteria to drought tolerance on the seedling for thirty genotypes of Bambara groundnut using polyethylene glycol (PEG) 6000 by three concentrations (0%, 5% and 10%). A complete randomized design was used for this experiment with three replicates.Result: The 10% PEG was the most suitable concentration to select Bambara groundnut lines for drought tolerance. Genotypes give different responses to concentrations of PEG. In susceptible lines, there are germination constraints, such as Prevent and germination delayed, the formation of hypocotyl length, root length, fresh weight and dry matter, while drought-tolerant lines can germinate normally. Obtained six lines that were tolerant to drought, five local, namely BBL 1.1, PWBG 5.2.1, PWBG 6, SS 2.4.2, SS 3.4.2 and one from Thailand which is Tvsu 86.
期刊介绍:
Legume Research An International Journal. The Journal is an official publication of Agricultural Research Communication Centre. It is designed to bring out the original research articles on genetics, breeding, physiology, bacterial avtivity, production, quality, biochemistry and seeds of legumes crops. The objective of the journal is to serve as a forum for scientific community to publish their research findings on legumes ans to provide basis for new research. Journal is being scanned in the important indexing and abstracting services.
