Mungbean is very nutritious pulse crop covering larger area in Pakistan. Average yield is very low than other mungbean growing countries. Among many yield limiting factors, Mungbean Yellow Mosaic Virus (MYMV) is at the leading position which can cause up to 100% yield losses in case of severe attack. Six cultivar (M-98004, NM-2006, Azri-2006, M-6, M-97001 and M-07007) were screened for their morphological characters affected by MYMV infection. Experiment was conducted in a randomized complete block design (RCBD). Data on plant height, pods plant-1, pod length, seeds pod-1, 1000-seed weight and number of branches plant-1 were recorded both from infected and healthy plants. All the parameters were found significantly affected by viral infection i.e. plant height was decreased by 19.58-28.43%, number of pods plant-1 by 37.81-44.68%, seeds pod-1 by 25.41-46.68%, 1000-seed weight by 35.41-49.94%, pod length by 28.89-47.59% and number of branches by 22.01-43.46%. By comparing the overall morphological response it can be concluded that three cultivars (M-98004, NM-2006 and M-97001) showed moderate reaction against MYMV, hence those can be recommended for better yield.
