To study the effect of drought, seven accessions of mungbean (Vigna radiata (L.) Wilczek), originated from Punjab and Baluchistan were subjected to four water stress regimes, i.e. (T1) control; (T2) 6 day; (T3) 9 day; and (T4) 12 day water stress arranged in a completely randomized design. Drought reduced the number of leaves, fresh weight, pod length, seed yield and number of nodules per plant but increased root length. The characters behaved differently in different treatments. Accession 259/1 (Khuzdar) emerged to be the best, showing a mere reduction of 24.6 percent in grain yield in the most stressful condition, whereas 285/1 (Turgbat), 259/1 (Khuzdar), 342/2 (Zhob) and NM51 (NIAB) proved to be the medium tolerant. However, accessions 284/6 (Turbat) and 89/10 from Rawalpindi could not withstand heavy stress of drought.
