英语翻译
Forty-eight populations of barley landraces collected from Morocco were screened for resistance to powdery
mildew and a number of different resistance genes were detected.Landraces originated from the collection of the
International Center for Agricultural Research in the Dry Areas – ICARDA,Aleppo,Syria.Twenty populations of
tested landraces (about 42%) showed resistance reactions and 46 single plant lines were selected.Fourteen of these
lines were tested in the seedling stage with 17 and another 32 lines with 23 differential isolates of powdery mildew,
respectively.The isolates were chosen according to their virulence spectra observed on the Pallas isolines differential
set.Five lines originating from five populations of landraces showed resistance to all prevalent in Europe
powdery mildew virulence genes.Thirty-five lines (76%) showed resistance reaction type 2.The distribution of
reaction type scores indicated that about 81% of all reaction types observed were classified as powdery mildew
resistance (scores 0,1 and 2).In forty-one lines (89%) the presence of unknown genes alone or in combination
with a specific one was detected.Four different resistance alleles (Mlat,Mla6,Mla14 and Mla22) were postulated
to be present in the tested lines alone or in combination.Among specific resistance alleles the most common was
allele Mlat (resistance Atlas).This allele was postulated to be present in twenty-three (50%) tested lines.The use
of new identified sources of resistance to powdery mildew in barley breeding is discussed
