A total of 329 chickpea lines, comprising 130 kabiili and 199 desi types, originating from six regions, viz., Indian sub‐continent, Middle East, North Africa, America, Europe and USSR, were sown in augmented design. The data recorded on agronomic characters on all entries from each region were evaluated in terms of group (region) means. Among the six regions, greater plant height and lateness in flowering were specific to USSR entries. Group means of USSR accessions, both desi and kabuli, differed significantly from those of Indian varieties for a majority of the characters. These observations indicate that the degree of expression of certain characters could be ascribed to specific areas, which led to area‐specific adaptations. Furthermore, type‐specific differentiating characters, differing in degree of expression, were observed in desi and kabuli types. For example, high mean values of characters, like branches, pods, grain yield and harvest index, were associated with desi types, and 100‐seed weight with kabulis. History of cultivation and selection for specific purpose has been cited as cause for area‐specific adaptations and type‐specific differentiating characters.
