Abstract
Fifty four wheat genotypes comprising of 41 Indian origin and 13 exotic genotypes were characterized using 39 polymorphic SSR markers for DNA fingerprinting and extent of genetic diversity. A total of 112 alleles ranging from 1 (Barc1, Barc26 and Barc147) to 7 alleles (Barc77) were generated with an average of 2.87 per SSR marker. UPGMA based cluster analysis, broadly grouped 54 genotypes into four clusters were represented as A, B, C and D. Cluster D included maximum number of genotypes (43) which was further divided into seven sub-clusters. Out of thirteen exotic genotypes used in the present study, six were included in sub-cluster D4. However, two exotic genotypes each were sub-clustered with Indian genotypes into three subclusters, D-2, D-6 and D-7 revealing their genetic similarity with genotypes of Indian origin. Genotypes from same origin were usually clustered together, e.g. K-65 and K-68 belonged to Kanpur region were clustered into 'Cluster B'. Similarly, MP-4115, MP-4131, MP-4136 and MP-4010 released for Madhya Pradesh were clustered into 'D-3' sub-cluster.
