Association of seed borne mycoflora of groundnut

Abstract

Groundnut (Arachis hypogaea L.) crop is attacked by a variety of seed and soil borne fungal pathogen as well as other pathogens, under field condition as well as during storage causing economical losses. Therefore, present investigation was planned to study the Association of seed borne fungi of groundnut. The seed samples of six different varieties were collected to study the seed borne mycoflora. Ten different types of fungi were associated with seed were detected by following standard blotter paper method, 2, 4-D blotter method and agar plate method. All together, ten fungi comprising Aspergillus flavus, A. niger, A. fumigatus, A. nidulans, Fusarium oxysporum, Sclerotium rolfsii, Rhizoctonia bataticola, Curvularia lunata, Alternaria alternata and Rhizopus stolonifer were observed common in all seed detection method. The difference in methods of recording fungi was also significant and standard blotter paper method was most efficient in recording more number of fungal colonies.
