Thirty five mungbean genotypes were used to study the relationships between yield and its component traits along with some physiological traits by using GT biplot technique. The GT biplot effectively revealed the interrelationships among the traits. Seed yield was found to be positively correlated with number of clusters per plant, number of pods per plant, days to maturity, number of pods per cluster, leaf area duration and chlorophyll content. Hence, effective selection criteria using these traits could be formulated in the mungbean breeding programme aimed to develop high yielding varieties. Among the genotypes studied LM 95 and GVIT 203 were identified as the ideal genotypes. The genotypes GVIT 203, LM 95, AKM 9904, KM 122 and WGG 2 showed superior performance for the traits such as seed yield per plant and number of clusters per plant indicating that these genotypes could be used as parents in the breeding programmes to develop high yielding genotypes in mungbean through selection focusing on more number of clusters per plant.
