Abstract
Thirty mungbean (Vigna radiata (L.) Wilczek) genotypes were evaluated at two locations of North West Frontier Province of Pakistan during 2007 and 2008 using randomized complete block design with three replications. Highly significant differences (p≤0.01) were observed among the genotypes for morpho-physiological traits across years at both locations as well as across years and locations. Location × year effect was highly significant (p≤0.01) for days to flowering, plant height and nodes plant-1. Genotype × location interaction was highly significant (p≤0.01) for days to flowering, maturity, plant height and leaf area, indicating differential performance of mungbean genotypes over the two test locations. Means for flower initiation, physiological maturity, plant height, leaves plant-1, nodes plant-1 and leaf area at Peshawar and Swat were 47.2 vs 50.5 days, 86.5 vs 84.2 days, 55.5 vs 52.3 cm, 8.1 vs 8.5
