Cabbage is one of the most important vegetable which is extensively cultivated in India and other countries. Fusarium yellows caused by Fusarium oxysporum f.sp. conglutinans is one of the most destructive diseases of cabbage and other crucifers. It causes severe loss in the yield in terms of both quantity and quality. The work on Fusarium oxysporum f.sp.conglutinans in India is very scanty. The aim of the present study was to isolate and study the morphological diversity and pathogenicity variability among F. oxysporum f.sp. conglutinans isolated from different cabbage fields. During the present work, an attempt was made to isolate, identify and characterize the Fusarium yellows of cabbage causing pathogen Fusarium oxysporum f.sp. conglutinans, a total of nine soil samples were collected from different fields out of which five were found to be positive for Fusarium oxysporum f.sp. conglutinans. The morphological, physiological characterization results of the present study including, pathogenicity reaction effectively demonstrated the confirmation of isolated pathogen as Fusarium oxysporum f.sp. conglutinans. A multiplex PCR method was developed for the easy detection of the Fusarium yellows and the black rot pathogen Xanthomonas campestris pv. campestris which in the initial stages produce symptoms which appear similar.
