Five mungbean varieties released by Punjab Agricultural University (PAU911, SML668, ML818, ML613 and SML832) were characterized using morphological and molecular markers. Phenotypically these varieties showed variation for growth habit, leaf and flower characters, pod colour, position and length, plant height, seed coat lusture and seed size during different growth stages of the crop. Plant morphology characters being polygenic in nature are liable to be influenced by the environment. Hence there is a need to use alternate descriptors which are rapid, accurate and less affected by environment. Therefore, in the present study, simple sequence repeats (SSR) markers were also used for determining genetic diversity analysis and supplementing morphological data. Five mungbean varieties were analysed using 44 SSR molecular markers, covering the whole genome of greengram. Out of 44 primers screened primers RG6, RG7, RG8, RG11, RG14, RG15 and MBM00101exhibited distinct banding pattern. Markers RG6 and RG7 differentiate the variety ML818 and SML832. Marker RG11 distinguished ML818 and ML613. Similarly, primers RG8, RG11, RG14 and RG15 showed distinctive banding pattern among the SML832 and ML613. Primer MBM001101 indicated polymorphism among PAU 911 and SML668. The UPGMA dendrogram based on similarity co-efficient showed maximum genetic difference between ML613 and ML818 and maximum similarity between ML818 and SML668.
