Analysis of genetic diversity in mango ( Mangifera indica L.) using isozymetic polymorphism

The isozymetic study was designed for assessing the genetic diversity among the selected mango cultivars/genotype available in Bangladesh. All the isozymes, used in the present study showed polymorphism for mango. A total of 25 different electrophoretic zymotypes were observed for three isozymes studied. Glutamate oxaloacetate transaminase, malate dehydrogenase and peroxidase analysis possessed 8, 10 and 7 zymotypes, respectively, and genotypes were grouped into different electrophoretic zymotypes which indicated higher level of genetic diversity of mango. For glutamate oxaloacetate transminase, G6 was the most common zymotypes whereas G3, G5, and G8 were found in few cases. Similarly, M8 and M6 in malate dehydrogenase as well as P6 and P5 in peroxidase were found more frequent while other zymotypes in both isozymes…
