Abstract

Random amplified polymorphic DNA (RAPD) fragments were used to assess genetic relationships among Cicer spp. growing in Turkey. Seven 10-mer primers selected from a 50 random oligonucleotide primer set, depending on their ability to amplify genomic DNA in all species, were used to detect RAPD variation in 43 wild and cultivated accessions representing ten species. These primers yielded 95 reproducible amplification products, 92 of which were polymorphic. Pairwise,genetic distances of accessions estimated according to Nei and Li (1979) were used to produce a dendrogram using UPGMA. The dendrogram contained two main clusters, one of which comprised accessions of the four perennial species (Cicer montbretii, Cicer isauricum, Cicer anatolicum and Cicer incisum) together with the accessions of the three annual species (Cicer pinnatifidum, Cicer judaicum and Cicer bijugum), and the other cluster included the remaining three annual species (Cicer echinospermum, Cicer reticulatum and Cicer arietinum). Analysis of RAPD variation showed that C. incisum is the most similar perennial species to annuals, and C. reticulatum is the closest annual species to chickpea. These results generally agree with our allozyme study which was carried out using same Cicer collection and previous studies of relationships among annual species. The results also show that RAPD markers can be used to distinguish Cicer species and to survey genetic variation and relationships among taxonomic units in this genus.
