Abstract
Leaf tissue extracts of Musa acuminata Colla diploid subspecies malaccensis, diploid M. balbisiana Colla, the triploid dessert banana cultivar ‘Valery’, the interspecific hybrid (acuminata × balbisiana) cooking banana cultivars ‘Chato’ and ‘Peli-pita’ and the triploid putative balbisiana-derived cultivars ‘Saba’, ‘Saba Puti’, and ‘Cardaba’ were subjected to isozyme analysis for four different enzymes. Isozyme banding patterns of the interspecific hybrids were generally additive and were a composite of the species-specific forms of each enzyme. Banding patterns for shikimate dehydrogenase, malate dehydrogenase, peroxidase, and phosphoglucomutase indicate that ‘Saba’, ‘Saba Puti’, and ‘Cardaba’ are acuminata × balbisiana hybrids.
