<i>De novo</i> expression of resistance to leaf rust (LR) and stripe rust (YR)^U,V.

UStripe rust race naturally infecting wheat plants in the field was not determined. For seedling tests, the LR PRTUS-50 source of MKPS and the 06-1-1 source of TDBG were used. VTests conducted on eighth-cycle sublines descended from leaf-rust susceptible ‘Lakin’ wheat compared to check cultivars and susceptible ‘Lakin’ progenitor. WSeedling analyses. XR = resistant, S = susceptible, and M = mesothetic (both flecks and pustules present on leaves). YNA = not applicable. ZNT = not tested.
