Abstract : Leaf phosphoglucose isomerase [glucose-6-phosphate isomerase] (PGI) isozymes from 139 cultivars and seedlings of mango (Mangifera indica) were analysed by starch gel electrophoresis. Six distinct banding patterns of PGI-2 were detected, consisting of single- and triple-banded phenotypes. The genetic control of the PGI-2 isozymes was inferred from segregating progenies of self-pollinated parent cultivars having triple-banded phenotypes. Comparison of the banding patterns of PGI-2 isozymes extracted from the pollen and the leaf of the same heterozygous cultivar demonstrated the allelism of the Pgi-2 locus.
