title: Molecular Variability in North Indian Isolates of Cylindrocladium quinquieseptatum Causing Eucalyptus Leaf and Seedling Blight.
abstract: Cylindrocladium quinqueseptatum has been considered as the most destructive pathogen of Eucalyptus nurseries and plantations in north India. Genetic resistance has not been determined against this disease in Eucalyptus and genetic diversity among the fungal population in northern India is not known. Seventy three isolates from infected leaves and twigs of Eucalyptus were collected from different northern Indian state and analyzed through RAPD-PCR for screening genetic diversity. The UPGMA cluster analysis score of 284 loci permitted identification of 11 population lines and an outlier. This molecular variability prevalent among the north Indian population of the pathogen can used in identifying Cylindrocladium leaf and seedling blight resistant Eucalyptus germplasm.
