Responses to leaf rust (LR) of selected sublines directly descended from the ‘R1’ ‘Lakin’ plant^R.

RAdult plants were tested against LR race MKPS in the field at Hays, Kansas and seedling reactions to LR race TDBG were evaluated in greenhouse tests at Winnipeg, Canada. SKansas LR isolate PRTUS-50 (typed as race MKPS) and Canadian isolate 06-1-1 (TDBG). TR = resistant, S = susceptible; rating taken at Hays, KS. UMS = Mesothetic, responding with both flecks and pustules. VThe numerator indicates the number of plants susceptible to LR and the denominator, the total number of plants inoculated. WNR = No rating as de novo trait of ‘progressive necrosis’ killed tissue before rust inoculation. X = ‘Lakin’ controls, top to bottom = 1-08-5, 1-07-5, and 2-03-5, respectively. YNT = Not tested. Z93FHB37 = Winnipeg experimental line used as resistant check.
