EVALUATION OF F4 PROGENIES EMANATED FROM AN INTERSPECIFIC HYBRIDIZATION OF MUNGBEAN AND BLACKGRAM

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.
