Abstract: Using ISTA technique, component plating of groundnut seed revealed that seed coat (testa) was greatly infected with 25.84 per cent incidence of seed mycoflora followed by cotyledons (16.36%) and embryo (9.98%). Aspergillus niger remained the most frequently occurring fungus in both seed coat and cotyledons with 7.23 and 4.48 per cent incidence, respectively. A. flavus (4.46%) and Macrophomina phaseolina (3.89%) occupied second and third positions, respectively in the seed coat while Fusarium (2.82%) and A. flavus (2.66%) ranked second and third, respectively in cotyledons. Fusarium (2.55%) was the most frequently occurring fungus in the embryo followed by A. niger (2.41%) and M. phaseolina (2.41%). Penicillium remained the least occurring fungus in all the three components of the seed followed by Rhizopus. There was a gradual reduction in the occurrence of saprophytic fungi from seed coat to embryo and increase in the incidence of deep seated pathogenic fungi like Fusarium and M. phaseolina.
