Molecular and morphological variation of six perennial and five annual species including domesticated chickpea,C. arietinum, were inferred on the basis of RAPD and S.E.M. seed coat features using three outgroup taxa (Lens ervoides,Lathyrus japonicaandPisum sativum). Of the 66 decamer arbitrary primers tested, eight primers revealed 87 informative fragments. Neighbor-joining cluster analysis using Jaccard's coefficient of similarity on the basis of polymorphic fragments indicated a narrow variation inC. arietinumand recognized two major clusters in the genusCicer.The first one included four species of sect. Monocicer:C. echinospermum,C. arietinum,C. reticulatumand Iranian material ofC. bijugum. The second cluster contained annual and perennial species belonging to sections Chamaecicer, Polycicer and Acanthocicer. The character state of morphological and ecological traits on the RAPD phenogram indicated no monophyletic incision. Our results suggested that the high genetic difference between annual and perennial species might be regarded as a rapid speciation of section Monocicer. Reconsideration of traditional classification of sections Polycicer and Acanthocicer is necessary. The ‘Desi’ and ‘Kabuli’ types ofC. arietinumcould not be separately grouped at the DNA level, and the low level of genetic variation ofC. arietinummay result from a bottleneck during the domestication process.
