A study was carried out periodically using PDA (Potato Dextrose agar) media to see the presence and absence of spore and mycelium growth in chickpea root, stem and leaf tissue infected with Fusarium oxysporum f.sp ciceri . The tissues were obtained from infected plots at different stages of plant growth. Results showed that fungal mycelium was isolated on PDA medium, starting from the first day, medium starting from the first day after germination media from 1 to 19 DAG (Days after Germination). Root and stem tissues collected from sick plot was shown fungal growth on media at 8 to 10 DAG in all the cultivars. Highly susceptible cultivars JG -62 and GG-4 were exhibited rapid fungal growth, vascular browning, and the occlusion of xylem vessels of root tissues with fungal hyphae than the other susceptible cultivars. Study also revealed that only PDA media growth was not enough to decide the particular stages of infection but microtome or histological observation indicated the clear cut ideas for deciding stages of infections.
