The genus Capsicum commonly known as chili pepper is a major spice crop and is of cosmopolitan in distribution. Assessment of genetic diversity in 21 cultivars of chili peppers was studied by electrophoretic patterns of peroxidase (PO) and polyphenol oxidase (PPO) isozyme marker technique. A maximum of 5(PO) in Ca9 and 4(PPO) in Ca14, Ca15, Ca16, Ca19 and Ca20 were scored respectively. Highest average per cent similarity (100%) was recorded between Ca15&Ca19 and the UPGMA dendrogram represented low genetic diversity. The present study revealed that considerable intraspecific differences were found in the cultivars. Thus the results obtained could be used for fingerprinting the genotypes.
