Citrus is the most important fruit crop of Himachal Pradesh and citrus canker caused by Xanthomonas axonopodis pv. Citri is major disease in all citrus growing areas in subtropical zone of Himachal Pradesh. To find out the amount of variability present in the bacterium, nine isolates collected from different species of citrus in subtropical areas were studied in vitro in relation to various cultural traits of the pathogen. It was found that all isolates exhibited considerable amount of variability in terms of all cultural parameters under study. Furthermore, Wakimoto growth medium was found to be the best for the growth of pathogen with pH 7.0 incubated at 25ËšC temperature. All isolates were found to produce light yellow, yellow, pale and dark yellow circular colonies with varied elevations and colony diameter ranging between 1.00 to 6.00 mm on five different media under study.
