Inheritance of leaf rust (LR) resistance in F₂ populations^W.

WTested plants were from single heads of phenotyped individuals of F1 populations in which the resistant parent was an individual from a ‘Lakin’-derived subline expressing de novo resistance. XThe (S) or (R) following the name of the wheat parent indicates a susceptible or resistant reaction, respectively to the 06-1-1 isolate of LR race TDBG. YR = resistant, S = susceptible, and M = mesothetic (both flecks and pustules present on leaves). Z(n) Denotes plant(s) with progressive necrosis trait; not scored for rust resistance phenotype.
