Abstract : During present investigation, among the six wheat genotypes tested against six isolates of Bipolaris sorokiniana, the genotype BOW‘S’ showed resistance response against three isolates, namely, BS-D-1, BS-DWR-K-2 and BS-K-4, whereas moderately resistance response against remaining 3 isolates i.e. BS-F-3, BS-P-5 and BS-V-6.The genotype A-9-30-1 showed almost highly susceptible response against each isolate except BS-D-1 which exhibited susceptible reaction on this genotype. Thus, it is clear that genotype BOW ‘S’ has broad genetic base for resistance, whereas genotype A-9-30-1 has no gene for resistance against these six isolates tested. Remaining five genotypes showed varying response, ranging from highly susceptible, susceptible, moderately susceptible, moderately resistant and resistant against various isolates of B. Sorokiniana tested.
