Abstract: One hundred twenty wheat seed samples collected from Sindh wheat growing areas were tested for fungal seed-borne pathogens by using the standard blotter method. Five seed borne fungi viz., Alternaria tenuis, Aspergillus niger, Fusarium moniliforme, Curvuluria lunata and Stemphylium herhurum were isolated from 12 wheat varieties viz., Mehran, T.J-83, Soghat, Sarsabz, Anmol, Johar, C-591, Sindh-81, Pak-70, Mexipak-65, H-68 and Faisalabad-85 respectively. Alternaria tenuis was predominance with an infection range from 22.5-47.5%. Maximum seed germination was observed in Anmol and minimum in Pak-70. Maximum root and shoot length of seedlings was recorded in Anmol and Sarsabz followed by H-68 and minimum in Pak-70, Mehran-89, Soghat and Johar.
