【 摘 要 】

Black rot has been a main disease constraint of cabbage grown by farmers in Ranchi. Cabbage is popular cultivars of the species (Brassica oleracia) belong to Cruciferae family. The family cruciferae also includes tomato, cauliflower, beans, broccoli, radish, turnip and pepper. In plain area it is grown mainly as a winter crop, whereas in the hilly areas it is grown as a spring and early summer crop. Cabbage is one of the common and most popular winter vegetables grown in India. In Jharkhand the cabbage is grown almost whole year except in the months when temperature rises up to 40-45 degree Celsius. The purpose of this work was to survey, culturing of isolate from cabbage and confirming the severity of Black rot disease in cabbage in the tribal populated area of Kanke block under Ranchi district of Jharkhand state. In morphology and growth characteristics the all the three isolate resemble those describe by Patel et.al.(1949) and Pandey (1980).It is evident from this the isolates of New Zealand and three local isolates of cabbage were morphologically alike being short rod with rounded ends. They are Gram negative and show positive KOH solubility. On the basis of the possession of many phenotypic properties the three cabbage isolates have been tentatively assigned to this pathogen Xanthomonas campestris pv. Campestris (Xcc) .
