Assessment of genetic diversity among chickpea cultivars of India using RAPD markers

Published on

Sixty eight chickpea cultivars of India belonging to both
Kabuli and Desi types were studied for the diversity using
60 RAPD primers. Among them 50 were found to be
polymorphic. On the average 3.55 loci per marker was
found for the entire population of 68 cultivars. Based on
the banding pattern, the cluster analysis was done using
UPGMA and the dendrogram was prepared. The similarity
coefficient ranged from 0.71 to 0.90 among the genotypes.
The PCA analysis also supported the finding from the
dendrogram. It was found that the desi and Kabuli types
did not segregate into two distinct groups which indicated
that perhaps very few genes were responsible for the
differentiation of chickpea in to Desi and Kabuli types
during their evolution. In order to broaden the genetic base
of the chickpea germplasm of India, efforts should be made
to utilize the exotic germplasm and the wild relatives.
