Abstract:
Seven cultivars of betelvine were screened for host resistance against the
the leaf spot pathogen Xanthomonas betlicola. The study revealed that none of the cultivars were absolutely resistant to the disease, but the minimum disease severity
was observed in the cultivar Tulasivettila. The minimum defoliation within 20
and 30 days after inoculation were observed in the cultivars Karilanchikarpuran
and Tulasivettila.
