Wheat is the most important food crop in India. During 2017-18, India’s harvesting recorded wheat grain production 99.70 mt from 29.58 mha cultivated area. India’s participation in the international wheat trade however is not up to the mark as being a major wheat producer. One of the major constraints in exporting wheat is prevalence of Karnal bunt (KB), internationally quarantined disease in the Indo-gangetic plain, major wheat bowl of the country. Karnal bunt caused by Tilletia indica (Mitra) is heterothallic fungus which requires fusion of different mating types for causing infection which results variants in their different potential to cause disease. Keeping this in view present study was undertaken to characterize different isolates of T. indica on the basis of mycelial growth, mycelial weight and sporulation. It was observed that there was non-significant variation in mycelial growth and mycelial weight, but significant variation in sporulation was observed among various isolates of T. indica. KB1 and KB2 isolates were most sporulating as compared to other isolates of T. indica. Characterization of Tilletia indica isolates will help in understanding the mechanism(s) of pathogenesis for devising novel strategies for management of Karnal bunt of wheat.
