Clustering of Chickpea (Cicer arietinum L.) Accessions

The variation in 20 morphological and agronomical traits has been evaluated in a set of chickpea genetic resources from four countries. Data indicated differences between accessions in leaf, flower, pod, and seed traits and characteristics, as well as in vegetation period. Multivariate analyses of these data segregated chickpeas into groups. Polymorphism in seed glutelines was absent, while variation in seed prolamines was very limited. DNA amplification patterns have been analyzed by semi-arbitrary primers and by specific microsatellite primers. Only some of semi-arbitrary primers generated usable DNA banding patterns, moreover interpretation of these patterns can be more or less difficult. On the contrary specific primers amplifying microsatellites at the specific loci generated unambiguous and reproducible differences between chickpeas.
