Özet
Stripe rust caused by Puccinia striiformis f.sp. tritici is the most serious disease
of wheat globally including south-eastern Anatolia of Turkey, where
wheat originated. In this study, 12 spring wheat genotypes were artificially
inoculated and preserved in two locations, Diyarbakır and Adıyaman,
during the 2011–2012 season to investigate loss in yield and yield
components. Genotypes were evaluated at the adult plant stage using two
partial resistance parameters: final disease severity and area under the disease
progress curve (AUDPC). AUDPC ranged from 14.8 to 860 in
Diyarbakır, and 74 to 760 in Adıyaman. Yield loss ranged from 0.6 to
68.5% in Diyarbakır and 9.8 to 56.8% in Adıyaman. Genotypes G1, G5,
G7 and G8 were found to lose less yield, while higher yield loss was
observed in G3, G4 (Nurkent), G5 and G9 (Karacada g-98). The highest
loss in thousand kernel weight was observed in a susceptible cultivar
Karacada g-98 in Diyarbakır followed by 43.4 and 24.4% in Adıyaman.
Test weight loss reached 8.89% in Diyarbakır and 20.8% in Adıyaman.
Yield loss and AUDPC had a positive significant relationship. Based on the
values of AUDPC, final disease severity and yield loss, three major clusters
were formed for 12 wheat genotypes. Partially resistant genotypes were
found to lose less grain yield and seemed to be stronger against severe
stripe rust pressure.
