Green gram is used as one of the important source of protein along with other pulses. The potential yield is affected by many seed borne pathogen. Stored and freshly harvested green gram seeds from different places of Odisha were collected to study the association of different fungal pathogen. Five fungal pathogens i.e. Aspergillus niger, Aspergillus flavus, Fusarium sp, Rhizoctonia sp and a sterile mycelium were found to be associated with seeds. Germination was lower in seeds with higher fungal infection than in seeds with lower infection in both freshly harvested and stored seeds. Surface sterilization reduced fungal infection and improved germination. Highest germination percent (88.0%) and lowest infection (12.5%) were found in surface sterilized greengram seeds collected from stored condition and germination percentage of 84% with 14.5% infection rate was found in seeds collected from field of Sinapali, Nuapada, Odisha. Highest healthy seed (84.25%) was observed in Sinapali, Nuapada, seed sample and lowest (54.25%) was found in Bhadrak seed sample. Healthy seeds inoculated by casual pathogen showed reduced germination and other quality parameter. Maximum reduction in germination (32.95%) and seedling vigour index (50.88%)was. caused by Aspergillus flavus. Seed rot was highest by Aspergillus niger (25.25%).
