Spot blotch in wheat (Triticum aestivum L.) is mainly caused by Bipolaris sorokiniana (Sacc.) Shoem in India and south Asian countries and inflected losses in yield up to 50 per cent. The isolates of B. Sorokiniana (BS1 to BS10) isolated from blighted leaf samples collected from different part of Jammu sub-tropics. Cultural and morphological variability of B. sorokiniana isolates exhibited that the colonies were effuse grey-white to effuse black and velvety-white mycelial growth with regular to irregular margins. The colour of colonies varied from grey to dark brown and white to light grey. The number of septation in isolates ranged from to and spore size ranged from to in length and to in breadth. | Variability in bipolaris sorokiniana causing spot blotch in wheat (Triticum aestivum L.) in Jammu sub-tropics
