Abstract

Twenty-four clones of banana and plantain representing various levels of ploidy and diploid M. balbisiana, were analysed for enzyme variants of malate dehydrogenase, phosphoglucomutase, glutamate oxaloacetate transaminase, shikimate dehydrogenase and peroxidase. Polymorphism was detected in all 5 enzyme systems. In addition, the four principal Cavendish clones, Robusta, Giant Cavendish, Dwarf Cavendish and Pisang masak hijau were found to be monomorphic for isozymes of 10 additional enzymes. Isozymes of glutamate oxaloacetate transaminase were the most useful for discriminating among clones of a particular genomic group.
