Abstract

Four temperatures and five different media were tested for cultural variability of nine geographical isolates of Urocystis agropyri (Preuss.) Schroet causing flag smut of wheat. Urocystis agropyri is extremely slow growing pathogen and each isolate responded differently at different temperatures. All the isolates/ collections grew well at 20°C after 45, 60, and 70 days after incubation. Ambala isolate was fast growing. PDA medium was found to be most suitable for the growth of all the nine isolates/collections. The average mycelial growth was also maximum on Potato Dextrose Agar Medium followed by Corn Meal Dextrose Agar, Oat Meal Dextrose Agar, Grain Meal Dextrose Agar and minimum on Wheat Meal Dextrose Agar.

Key Words: Variability, media, isolates, wheat.
