In the present investigation, 100 germplasm lines were evaluated and characterized by using six yield and yield contributing traits. Three parameters viz., days to maturity (medium -48 % and late 52 %), presence or absence of flowers on the main axis (absent-20 % and presence- 80 %) and 100-kernel weight (medium-97 % and high- 3%) were found dimorphic, whereas, shelling outturn showed three states of expression viz., low (23%), medium (64 %) and high (13%). The characters of dry pod yield/plot was in the range of 159 g (ICGV 201130) to 755 g (ICGV 201174) and kernel yield/plot was in the range of 97 g (ICGV 201130) to 562 g (ICGV 201174). The genotypes were grouped based on the data and further, based on the objective, the lines will be used in the breeding programme.
