The present investigation was undertaken with the main objective to determine studies on seedborne fungi of soybean were conducted at DSST and Plant Pathology, College of Agriculture, Rajendranagar, Hyderabad. A total of 120 representative soybean seed samples (cv. JS - 335) from major soybean growing districts of Andhra Pradesh viz., Adilabad (60 samples) and Nizamabad (60 samples) were collected during Rainy season 2012. Total per cent incidence of seed mycoflora in Nizamabad and Adilabad districts ranged from 30 to 49.2 % and 23.6 to 45.0 % by blotter method, 14.8 to 28.1% and 11.6 to 22.1% by 2, 4 - D blotter method, 11.8 to 19.3 % and 9.5 to 16.2 % by deep freeze blotter method, 13.1 to 37% and 15.4 to 26.4 % by agar plate method, respectively. Out of nine fungal species recorded, M. phaseolina was found predominant in the samples analysed from two districts (8.5 to 28.5 %), while the occurrence of Cladosporium sp. (0.3 to 0.5%) was least. Out of four methods employed for detection of seed mycoflora, standard blotter method was found superior over other methods.
