Abstract

Forty seed sample of wheat (Triticum aestivum) were collected from four locations viz. Chitwan, Kaski, Banke and Lalitpur and tested by blotter method at laboratory during 2013 for determining fungal pathogens associated with wheat seeds in Nepal. Eighteen species representing thirteen genera of fungi were recovered from the seed. Alternaria alternata and Bipolaris sorokiniana were predominant in all the varieties/genotypes from all the locations, where B. sorokiniana was strongly pathogenic in wheat crop. Percentage frequency and type of fungi detected varied with variety and locations. Bipolaris sorokiniana was highest (64.40%) in Banke than remaining three locations. Seeds of Chitwan had lowest percentage (5.50%) of seed infection as compared to other locations. Relative abundance of Alternaria alternata (55.10%) was highest as it was the most prevalent component of seed borne mycoflora, followed by Bipolaris sorokiniana (34.69%) and Cladosporium herbarum (7.19%). Differences in quantity of precipitation and relative humidity might be the possible reason for variation in frequency and type of fungi detected in wheat seeds of four locations.
