is an important disease of cultivated barley in several parts of world and sometimes,
it causes yield losses due to sever epidemics. In order to prevent disease epidemics
and decrease of yield losses; determining of effective genes, use and production
of resistant cultivars/lines, particularly durable resistance, will be the best
control method. Thus, for these purposes 31 barley genotypes including differential
sets and promising lines, were evaluated during 2007-2010 cropping years. This
study was subdivided into two experiments. The experiment-1 was conducted in three
parts of Iran; Ardabil, Sari, Mashhad, by monitoring of virulence factors on differential
sets during 2007-2009. But the experiment-2 was conducted on promising barley
lines by measuring of Disease Severity (DS), Coefficient of Infection (CI) and
relative Area under Disease Progress Curve (rAUDPC) in Ardabil during 2009-2010
cropping seasons. The results of virulence and avirulence monitoring in Ardabil
showed presence of virulence for Rps2, Rps1.b, Rps3 and RpsI5
but in Mashhad virulence was observed for Rps2, Rps1.b and Bancroft.
In Sari, except for Topper cultivar, virulence for resistance genes was not observed.
In this study it was also concluded that RpsEm1, RpsEm2, RpsHF,
Rps4, Rps1.c, RpsVa1, RpsVa2, RpsAst were effective
resistance genes. The effective genes can be used in breeding programs, e.g.,
pyramiding resistance genes. Among promising lines, except for EC-81-15, EC-82-11
and EW-80-13 which had low CI and rAUDPC, the rest lines had moderately susceptible
or susceptible reaction to barley stripe rust in Ardabil.]]>Anonymous,1991Ben Yehuda, P., T. Eilam, J. Manisterski, A. Shimoni and Y.
