Abstract

                                The per cent incidence of seed mycoflora and seed germination of two varieties of green gram or mungbean (Vigna radiata L. var. Pant-2 and Type-44) were studied in freshly collected, six months stored and one year stored seeds. In all, 25, 23 and 25 fungal species were isolated from the seeds of var. Pant-2 collected from godown, shopkeepers and crop filed respectively and 22 fungal species were isolated from var. T 44 collected from godown using agar plate and blotter techniques. Seed mycoflora superficially associated with the freshly collected seeds of both the varieties predominantly consisted of fungi belonging to genera Alternariu, Cladosporium and Curvularia. Dominant fungal species of Alternaria, Aspergillus, Penicillium, Cladosporium and Curvularia were found to be associated with stored seeds. Aspergillus flavus, A. niger, A. fumigatus and A. luchuensis were found to be dominant on one year stored seeds. Deuteromycetes ranked first in number followed by phycomycetes. The number of fungal species was found more by the blotter technique in comparison to the agar-plate technique. The fungal population increased with increasing storage periods.
