ABSTRACT

Chickpea wilt complex is associated with numerous pathogens, among which Fusarium oxysporum f.sp. ciceri is the major pathogen. The fungal species isolated in Agar Plate were belonging to 6 genera namely, Aspergillus niger, Penicillium , Fusarium moniliforme (was absent in Pant G114), Fusarium oxysporum f.sp. ciceri, Rhizopus sp. and Trichoderma harzanium ( were absent from genotype ICCL 87322 and variety H208 ) whereas fungal species isolated in the blotter test were i.e. Aspergillus niger, Penicillium , Fusarium moniliforme (was absent in Pant G114), Fusarium oxysporum f.sp. ciceri, Rhizopus sp. and Trichoderma harzanium. However, Trichoderma harzanium was absent in case of variety H208. Since seedborne infections attack in the initial stage of seed germination therefore, disease effect was observed on seedling emergence, seedling mortality, radical length and plumule length. Four varieties/genotypes of chickpea:- Local Variety , Pant G-114 variety, ICCL 87322 genotype and H 208 variety isolated Fusarium oxysporum f.sp. ciceri as internal seed borne infection . On artificial inoculation, maximum loss to all treatments was in H208 whereas minimum in Pant G 114.
