Description
Summary:Eleven primers RAPD were used to estimate the genetic variability between 31 isolates of M. musicola collected from 'PrataAna' and Nanica bananas that were cultivated in northern Minas Gerais, Brazil. A total o 83 fragments were amplified, of which 73 were polymorphic, corresponding to an average of 6.6 polymorphic fragments per primer. The genetic distances ranged from 0.06 to 0.56 and the average distance of 0.21. A dendrogram constructed based on the UPGMA clustering method revealed 8 and no correlation between molecular grouping and geographical origin was observed.
