The yielding ability and adaptability of 25 indigenous and exotic types of gram was studied under five environments and it was found that Ceylon 2, Ferozepur 4, Mandalay, Kanpur and N.P. 17 were not only high yielding but relatively stable over environments. The estimates of components of variation for ten yield components showed that there was wide variation in the material for all characters and that variability was affected by environment particularly for plant height and secondary branches per plant. On the whole heritability (broad sense) values were high but was the minimum for pods per plant; also, it was affected most by environment. High heritability and high genetic advance were-associated in case of setting percentage, flowering duration, primary branches and pods per plant, indicating thereby the possibility of success for selection in these characters.
