Characterization of coconut germplasm based on protein polymorphism

Characterization of different coconut cultlvars and hybrids was done by analyzing the banding profiles of native proteins using 10% poly acrylamide gel electrophoresis. Intrapopulatlon variation was studied in six Dwarfs, eight Talls, two hybrids and their parents. Among Dwarfs, MOD showed highest intrapopulatlon variation and GDD showed least polymorphism. Among Tails, JVT showed highest and KPDT showed least lntrapopulatlon variation. While among the hybrids and their parents, WCT showed highest and LCT and GBGD showed least variation. Interpopulatlon variation was studied in seven Dwarfs, 19 Talls and four hybrids. Allellc frequency was highest in NGAT and BENT, while least in FJT.
