Symptomatology and pathogenicity characteristics of Fusarium oxysporum F. sp. Ciceri in chickpea seeds

Fusarium wilt is a serious disease of chickpea in India and other 32 countries. It is soil borne disease. Observation of symptomatology was record. This pathogen was isolated on culture media and natural host, purified and its pathogenicity was proven in pot culture and on potato-dextrose-agar. Pathogenicity of the fungus carried out on a chickpea variety Radhey, which exhibited wilting after 25 days of inoculation. Out of 75 seeds, 68 germinated in infected condition. Symptom appearances were in 20 plants at seedling stage, 14 plants in adult stage, 34 not show any symptom of wilting. Seeds harvested from wilted plants were lighter and duller than those from healthy plants (Haware and Nene, 1980). Further, on the basis of morphological, cultural characteristics of the pathogen and symptomatology, we have confirmed that fungal pathogen, as Fusarium oxysporum f. sp. ciceri.
