| Abstract: | Twenty two RAPD and 22 ISSR markers were evaluated for their potential use in determination of genetic relationships in chickpea
(Cicer arietinum L.) cultivars and breeding lines. We were able to identify six chickpea cultivars/breeding lines by cultivar-specific markers.
All of the cultivars tested displayed a different phenotype generated either by the RAPD or ISSR primers. Though ISSR primers
generated less markers than RAPD primers, the ISSR primers produced higher levels of polymorphism (% of polymorphic markers
per primer) than RAPD primers. A high level of within cultivar homogeneity was observed in chickpea. Cultivars/breeding lines
originating from a common genetic background showed closer genetic relationship. Chickpea lines with similar seed type(kabuli
or desi) had a tendency to cluster together.
