Rice is an important food crop across the world. Good quality seed is the major criteria for better yield and production. Seed samples collected from the Cuddalore, Mayiladuthurai, Tanjore, Trichy and Karur district were tested for the presence of seed borne fungal mycoflora and their percentage of incidence using Blotter paper and Agar plate techniques. This experiment shows the higher incidence of Bipolaris oryzae in the collected samples followed by Curvularialunata, Aspergillus and Alternaria alternata, whereas Pyricularia grisea, Sarocladiumoryzae, Ustilaginoidea virens and Fusarium sp., were found in a relatively low level. The JGL 1798 variety had a high mean incidence of seedborne fungi whereas the BPT 5204 had a least mean incidence of the pathogen. The JGL 1798 variety recorded a minimum germination (68%), maximum seed mortality (32%), maximum percentage of abnormal seedling (34%), minimum root length (6 cm), shoot length (5.5 cm) and Vigour index (782).
