General reaction responses ofBlumeria graminisisolates collected from different hosts on triticale, wheat and rye cultivarsa
Source hosts (origin of isolates)b Inoculated hosts
Triticale Wheat Rye
B.g. f.sp. ‘triticale’ (n = 35) +++ ++
B.g. f.sp. tritici (n = 35) + +++
B.g. f.sp. secalis (n = 2) + +++

a + indicates infection, − indicates no infection; a higher amount of + corresponds to a higher aggressiveness. Aggressiveness is interpreted here both as a quantitative and qualitative component of pathogenicity. Quantitatively as a higher amount of colonies with well developed hyphae and abundant conidia. Qualitatively as more isolates which are able to infect a particular host or cultivar.

b Number in parenthesis indicates the number of isolates from each source host that were used in this experiment.
