ABSTRACT
Considering water scarcity, the current study was carried out to evaluate mung bean genotypes for morphological properties in a dehydration situation. The current experiment was carried out at the pot house of Baba Mastnath University, Asthal Bohar, Rohtak, during two kharif seasons of 2019-20 and 2021-22. The experiment was set up in a completely randomized design, with two environments and eight genotypes in three replications for root and shoot length, number of leaves/plant, number of flowers/plant, nodules/plant, number of secondary branches/plant, root, leaf and nodule fresh and dry weight. Drought condition was maintained by the withholding of adequate water supply, whereas in the control pots, water was applied up to field capacity. Drought application showed a reduction in mean root length (12.1 to 10.7 cm) and shoot length (24.5-18.0 cm), number of leaves/plant (8.8-6.7), number of flowers/plant (27.4-23.8), nodules/plant (8.8-6.9), number of secondary branches/plant (6.4-4.3), root (11.5-6.3 g; 5.07-2.82 g), leaf (7.35-5.33 g; 3.94-1.87 g) and nodule (5.17-3.04 g; 2.76-1.19 g) weight, respectively. In all tested genotypes PAU-911 and MH-318 genotypes were found to have tremendous potential under drought conditions.
