  1. Three virulence factors (vir9, vir4, vir6) were tested, with 16 natural isolates (i1-i16) of P. striiformis f.sp. tritici. For each of the 10 pairs (A-J), the two competing isolates had (nearly) identical AFLP profiles and identical virulence factor profiles, except for the virulence factor to be tested (marked in bold). The isolate carrying the additional virulence gene is referred to as virulent (vir), the one without it as avirulent (Avir). 1 Nomenclature determined by reactions on a set of European and world differential cultivars; 2 SD refers to virulence on the cultivar Strubes Dickkopf; 3 Lab references of each isolate. The two numbers after the "J" denote year of sampling of the isolate.
