Genetic diversity was assessed for 35 garcinia (Garcinia gummi-gutta (L) Roxb) germplasm maintained at Regional Agricultural Research Station, Kumarakom collected from different geographical locations using ISSR markers. Out of the 34 ISSR primers screened, 18 primers were polymorphic and used for further diversity analysis. The products were detected by electrophoresis and analysed using the program NTSYS-PC. Seventy two loci were polymorphic out of the 99 loci amplified. The average Polymorphic Information Content (PIC) obtained for 18 primers was 0.33 and the average marker index was found to be 1.3. Two major clusters were identified at 64% similarity. The clustering pattern did not follow any geographic distribution pattern. The genetic similarity index ranged from 0.55 to 0.95 indicating a genetic diversity of 45% within the germplasm accessions.
