Abstract
Paddy grain discolouration is an important disease and it has led to huge losses when the favourable conditions are available. It is caused by a complex of mycoflora. Paddy seeds of 7 varieties viz. PKV Kisan, D100, Sindewahi, RPN 7, RPM, MTU 1001 and 1010 were collected from different regions of Eastern Vidarbha. The maximum discoloured grade of each variety were tested for seed mycoflora by Standard blotter paper method and agar plate method. From the two methods, a total of 20 fungal species belonging to 16 fungal genera viz., Fusarium moniliforme, Fusarium solani, Fusarium semitectum, Fusarium equiseti, Curvularia lunata, Chaetomium sp., Alternaria padwickii, Tilletia sp., Rhizoctonia solani, Taeniolina sp., Aspergillus flavus, Sarocladium oryzae, Aspergillus niger, Bipolaris oryzae, Acremoniella sp., Pyricularia oryzae, Nigrospora sp., Pestalotia sp., Cladosporium sp. and Rhizopus sp. were detected. Pre-treatment was given to all the seven varieties of paddy and reduction of super

Conclusion
All the seed samples were tested for seed mycoflora by blotter paper method and agar plate method. From the two methods, a total of 20 fungal species belonging to 16 fungal genera viz., Fusarium moniliforme, Fusarium solani, Fusarium semitectum, Fusarium equiseti, Curvularia lunata, Chaetomium sp., Alternaria padwickii, Tilletia sp., Rhizoctonia solani, Taeniolina sp., Aspergillus flavus, Sarocladium oryzae, Aspergillus niger, Bipolaris oryzae, Acremoniella sp., Pyricularia oryzae, Nigrospora sp., Pestalotia sp., Cladosporium sp. and Rhizopus sp. were detected. After pre-treatment, there was reduction of superficial and saprophytic fungi growth along with pathogenic fungi in all the seven varieties. Thus, the study has shown that mycoflora associated with seed discolouration are major constraints in production of quality seeds of paddy. Therefore, the seed mycoflora are economically important since they affect the attributes of paddy seed and hence, research for the better seed heal
