ABSTRACT

A present investigation was carried to detect seed borne mycoflora in groundnut. A total of three varieties named Nitya haritha, Kadiri lepakshi and TCGS 1694 were collected from Regional Agricultural Research Station (RARS), Tirupati from the farmers participatory seed production programme. The samples collected from these varieties were used to detect seed borne mycoflora by using standard blotter method, agar plating method and rolled paper towel method. A total of seven fungi belonging to four genera viz., A. niger, A. flavus, A. fumigates, A. terreus, Rhizopus sp., M. phaseolina and Penicillium sp. were detected. Agar plating method emerged as the efficient method as it resulted in maximum isolation of seed mycoflora (28.42) followed by next highest (25.33) was recorded in standard blotter method and rolled paper towel method was considered less efficient among these three methods as it recorded (22.08) mean incidence. Aspergillus niger, Rhizopus sp. and Aspergillus flavus found to be predominant.
