Among the cultivars, higher enzyme polymorphism was observed in GDD and least in GBGD. Of the seven isozyme systems, PPO showed higher polymorphism followed by EST, GOT, PER and MDH. ACP and ADH did not show any intrapopulation variation.enCoconutdwarfsisozymePAGEintra-populationpolymorphismArticle
