Two hundred ten germplasm lines and three checks, namely, Udai, Awarodhi and K 850 received from ICRISAT, Hyderabad were evaluated for 9 yield and other related traits. Three characters (secondary branches per plant, primary branches per plant and pods per plant) exhibited high variability. Of the remaining character viz., days to 50 per cent flowering and days to maturity showed relatively low variability. Following the Non-hierarchical Euclidean cluster analysis, all the 210 genotypes were grouped into 13 clusters with variable number of genotypes. On the basis of data on genetics divergence and mean performance of yield and other traits, five diverse and superior genotypes, namely, ICC Nos. 595, 1180, 12141, 14190 and 16670 were selected. Each of these genotypes was exceptionally good for one or more character and was reasonable for other character relative to those of the best check varieties. Therefore, these genotypes may be involved in multiple crossing programmes to recover transgressive segregates. Further on the basis of correlation coefficient, it is suggested that selection of plants with high/more plant height, secondary branches/ plant, pods per plant and number of seeds per pod would show result in progenies with high seed yield potential in chickpea.
