Background and objectives Grain discolouration of rice is now receiving much attention since it leads to empty grain or aggravation of grain quality over rice growing areas. It is a serious problem in all rice tracts of the world [1]. This study was conducted to identify fungal species associated with grain dicsolouration in Tamil Nadu, INDIA. Materials and Methods Discoloured grains were sampled in October from 12 paddy fields in Tamil Nadu, India. Method approved by ISTA (1976) for sampling and standard blotter paper method for identification of discolurating fungi were used [2]. Results and conclusions The study envisaged that none of the seed samples tested was totally free from microflora. Aspergillus niger (IMI No: 372010), Aspergillus flavus (IMI No: 372012), Aspergillus fumigatus, Aspergillus terreus, Fusarium moniliforme, Drechsiera oryzae and Curvularia lunata were frequently occurring in the seed samples.
