Abstract
One hundred and twenty, one-parent families of naturally distributed Gamboge trees (Garcinia gummi-gutta L.) of Central Kerala were studied for their genetic divergence. D2 estimates based on 15 fruit characters were used for obtaining the clustering pattern and their inter and intra-cluster distances. It was found out that regional diversity (geographic diversity) was not related with genetic diversity. Genotypes hailing from Pathanamthitta and Alapuzha Districts exhibited wide range of diversity. Hydroxy citric acid content contributed maximum towards genetic diversity.
