Nineteen X. campestris pv. mangiferaeindicae strains collected from
different ecogeographical areas/mango genotypes of India were studied to
confirm the existence of variability in the strains on the basis of
their pathogenicity on genotypes (9), reaction towards antibiotics (9)
and growth on culture media (5). Study revealed the existence of
variability in Xcmi strains as exhibited by their differential reaction.
The similarity in Xcmi strains was observed by hierarchical cluster
analysis. Clustering pattern on these three detection methods indicated
that the grouping of strains is not entirely based on their
geographical distribution as the strains from northern and southern
parts of India falls in a single cluster. However, the strains collected
from Bihar exhibited more similarity with each other and clustered in
one or nearby cluster in all the detection methods used. |
