Abstract

Based on the host pathogen reaction on a set of 19 Canadian differentials twenty two isolates of Ustilago segetum f.sp. tritici collected from north India were grouped into four distinct races. Race T1 was detected in Himachal Pradesh; two races T7 and T11 were observed in Haryana isolates, races T7 and T4 were found in Rajasthan and T1 and T11 were observed in Punjab.
