A total of 100 F4 progenies (87 mungbean type and 13 blackgram type) of a wide cross between mungbean (cv BDYR-1) and blackgram (cv DPU 88-1) were evaluated in augmented block design. A wide spectrum of variability was observed for all the characters except for days to first flower. Progeny No.70 was significantly superior over best check for days to first flower, pods/cluster, pod length and seeds/pod. Character association unveiled highly significant and positive association of grain yield with pods/cluster and pods/plant. Metroglyph and index score analysis broadly divided 100 progenies into nine groups across pods/plant and grain yield/plant. Maximum numbers of progenies (60) and maximum variability for different yield contributing characters were found in fifth group. Based on SDS _PAGE analysis dendrogram divided 33 genotypes (31progenies and two parents) into eleven clusters at 85% similarity and the Jaccard's similarity coefficients ranged from 0.26 to 0.96.
