Abstract:

Chickpea (Cicer arietinum L.) contributes 18% of the global production of grain legume and provides as an important source of dietary protein for living things. The area and production of chickpea has been reduced due to several abiotic and biotic factors. Among them soil borne pathogen of F. oxysporum f. sp. ciceris causing severe yield loss now a days. In this study conducted for a prevalence of wilt incidence percentage varied from 34.00 to 57.33 per cent in chickpea due to F. oxysporum f. sp. ciceris in Tamil Nadu. Continuously the pathogenic ability, cultural and morphological characterization was carried out. Among the fifteen isolates Foc4 (Gomangalampudur) is highly pathogenic when compared to other and causing early wilt in JAKI-9218. Grouping of isolates based on their virulence potential isolates like, Foc4, Foc5, Foc6, Foc8, Foc10, Foc11, Foc12, Foc13 and Foc14 are highly pathogenic nature and other isolates were strongly pathogenic. The cultural variability of these isolates have pale yellowish to dark pinkish (Foc4) in pigmentation with aerial compact mycelial growth within 7 – 9 DAI. The morphological characterization all the isolates produced micro, macro-conidia and chlamydospores within 20 DAI and the size of the spores varied from (micro conidia) 5.6 x 2.5 µm (Foc2) to 12.7 x 3.1 µm (Foc14) and the isolate (Foc4) maximum size of macro conidia in 29.1x 4.9 µm and mycelial dry weight of 700 mg at 100 ml.
