All the tested fungi showed pronounced inhibitory effects on seed germination of brinjal cultivars as compared to control. All the five cultivars were inoculated with the Fusarium oxysporum, Phoma sp., Penicillium sp., Curvularia lunata, Alternaria tenuis, Aspergillus flavus and A. niger. Lowest seed germination was found in cultivar ABH-1 (). Significantly highest seed germination was observed in cultivar Doli-5 (). F. oxysporum, Phoma sp., Penicillium sp., C. lunata, A. tenuis, A. flavus, A. niger and control (uninoculated) showed average germination per cent , , , , , , and , respectively. Among all the fungi, the seed germination was observed minimum in the seeds inoculated with A. tenuis () followed by A. niger (). Maximum seed germination per cent was observed in Phoma sp. () as compared to control (). Highest seedling vigour index was observed in cultivar Doli-5 (411) followed by GAOB-2 (403). The lowest seedling vigour index was found in cultivar ABH-1 (313) followed by cultivar GABH-3 (318) and GOB-1 (390). | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 08 2019 Journal homepage http Original Research Article https Effect of Seed Mycoflora on Seed Health of Brinjal Cultivars .

Introduction Seed Infection adversely affects the seed quality causing seed discoloration reduced seed weight and density poor germinability and reduced viability. Most of the fungal diseases such as anthracnose leaf spots leaf blights and root rot causing severe losses are .
