Abstract :

Chickpea (Cicer arietinum L.) is one of the major legume crop widely grown in the Indian sub continent. The major diseases of the chickpea crop are Ascochyta blight, Fusarium wilt and dry root rot. Of these wilt caused by F. oxysporum f. sp. ciceri has been considered as divesting one to cause up to 10 per cent loss in yield. The transmission of the pathogen from seed to seedling was studied by seedling symptom test followed by serial isolation method on three susceptible varieties ICP–1454, Radhey and ICCP–1854 under laboratory conditions. The pathogen was transmitted from seed to seedlings within 15 days in the ratio 9:1 to 4.5:1 with in variety Radhey. The pathogen was found systemic as it was recovered from the healthy tissues as well diseased tissues from roots to the top of the seedlings in serial isolation method.
