Characterization of wheat-Thinopyrum bessarabicum genetic stock for stripe rust and Karnal bunt resistance

Abstract Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup most crops. Narrowed these crops has made them vulnerable towards disease insect epidemics. For sustainable crop production, variability must be broadened against various biotic abiotic stresses. One ways to widen configuration is identify novel additional sources durable resistance. In this regard wild relatives are providing valuable allelic diversity biotic, stress tolerance quality components. incorporating from relative’s wide hybridization technique become a promising method. purpose, wheat-Th. bessarabicum amphiploid, addition translocation lines have been screened in field screen house conditions get yellow rust Karnal bunt resistant. Stripe screening under revealed 4JJ 6JJ as resistant moderately while 3JJ, 5JJ, 7JJ Tr-3, Tr-6 wheat-Thinopyrum-bessarabicum stock. depicted 5JJ highly These stocks may used introgression stripe resistance tertiary gene pool into susceptible wheat backgrounds.
