tailieunhanh - Characterization of Indian isolates of Fusarium oxysporum f. sp. ciceri causing chickpea wilt

On the basis of cultural, morphological, molecular characteristics and pathogenicity test, the fungus was confirmed as F. oxysporum Schlechtend. Fr. f. sp. ciceri (Padwick) Matuo and K. Sato. The pathogenic nature of fifteen isolates tested on chickpea wilt susceptible cultivar JG-62, two isolate (Char, Choki) were found non-pathogenic gave zero per cent disease incidence (PDI), while one isolate (Chittal) found highly pathogenic with 100 per cent PDI which was further used for molecular identification and screening of agro-chemicals. Study of cultural characters and conidial morphology of different isolates were carried out which showed variation in growth habit, pigmentation, sporulation, shape and size of macro and micro conidia, structure and size of chlamydospores, etc. | Characterization of Indian isolates of Fusarium oxysporum f. sp. ciceri causing chickpea wilt
