SUMMARY

The present study was undertaken to provide information on nature and magnitude of genetic diversity among promising genotypes of mungbean using Mahalanobis’s D2 statistic planted in the research area of the Department of Dryland Agriculture, Chaudhry Charan Singh Haryana Agricultural University, Hisar (Haryana) during kharif 2014. These genotypes were grouped into six clusters. The highest intracluster distance was observed for cluster III (3.874) and the lowest was observed for cluster II (3.537). While the highest inter-cluster distance was observed between cluster I and VI (6.315). Cluster IV formed monogenotypic cluster. Cluster III showed the maximum mean value (35.407) for harvest index, plant height (31.85) and seed yield (2.51). The highest contribution toward the total genetic divergence was recorded for harvest index, plant height, days to maturity and biological yield per plant. Selection index (I) aimed at selection on several characters simultaneously indicated that genotypes, RMG-991, MH539, ML-776, MH-560, MH-934, ML-682 and Pusa-0672 had performed better and are important for further breeding programme aimed at improvement of yield.

Key words: Mungbean, genetic diversity, cluster analysis, rainfed condition
