Development of superior cultivars is the prime objective of any plant breeding program. This research was conducted with the aim to study genetic variability and trait association among the mungbean genotypes for yield attributes under rainfed conditions. Fourteen mungbean genotypes were tested in randomized complete block design with three replications at the University of Agriculture Peshawar during spring 2017. Data were noted on different yield contributing traits like days to maturity, plant height, pods plant-1, pod length, clusters plant-1, 100-grain weight and grain yield plant-1. Analysis of variance revealed highly significant difference for all the studied traits. Maximum number of clusters plant-1 were showed by genotypes Mung-Azri-06 (9) VC 6321(9), Mung NM-06 (9) and Mung-Chakwal-06 (9). Mung-Azri-06 revealed maximum pod length (8.6 cm), pods plant-1 (27.37), 100-grain weight 4.40 g) and grain yield (17.90 g). Grain yield showed significant correlation with cluster plant-1(r = 0.71**), pods plant-1 (r = 0.80**), pod length (r = 0.59*) and 100-grain weight (r = 0.97**). Promising genotypes Mung-Azri-06, Mung-Chakwal-06 and Mung- NCM-257-2 performed best than other genotypes and can be used in future breeding programs.
