Assessment of genetic diversity and hybrid identification in stevia using inter simple sequence repeat (ISSR) markers

Identification of intra-specific diversity is an essential condition for the analysis of genetic diversity. Stevia rebaudiana Bertoni belonging to the family Compositae, has a long and successful history of use as a commercial sweetening agent. Stevia is a self-incompatible plant. Originated from a...

A total of 332 clear bands were generated, out of which 275 (82.8 %) were polymorphic. The total number of markers varied from 6 to 18 with a mean of 10 markers per primer. The number of polymorphic markers for each primer varied from 3 (IS34/2) to 17 (IS55) with a mean of 8 polymorphic markers per primer. The amplified product size ranged from 50125 to 5000 bp. The PIC values ranged from 0.16 (IS34/2) to 0.5 (IS19, IS55, IS50, IS70 and IS78), with a mean PIC value of 0.43. The Jaccard‘s similarity coefficient values ranged from 0.375 to 812 with an average of 0.54. A dendrogram constructed based on the UPGMA clustering method, revealed two major Groups (A and B). Group-A showed segregated Bertam while Group B was further segregated into seven subgroups consisted of the remaining accessions studied.

ISSRs have the potential to distinguish closely related accessions based on the patterns of their amplicons. High polymorphism obtained indicates ISSR is an efficient technique or evaluating genetic diversity in stevia.
