dc.description.abstract	The study was aimed at characterizing and analyzing the genetic diversity at the isozyme level of thirty coconut cultivars. Ten enzyme systems viz., Alcohol Dehydrogenase, Glutamate Oxaloacetate transaminase, Glucose-6 Phosphate Dehydrogenase, Peroxidase, Esterase, Alpha-Amylase, Phosphorylase , Malate Dehydrogenase, Super Oxide Dismutase and Acid Phosphatase were studied using discontinuous polyacrylamide gel electrophoresis. Twenty loci and 40 alleles were observed, of which, 14 loci were polymorphic. Seven loci were heterozygous. Null alleles were observed for ACP, ADH and MDH.Greater heterozygosity was observed for Glucose-6 Phosphate Dehydrogenase and least for Super Oxide Dismutase. Among the cultivars,Nadora Tall and Calangute Tall showed maximum heterozygosity while Kulasekharam Green Dwarf showed least heterozygosity.	en_US
