Wheat (Triticum spp.) is the world’s one of the most important and strategic crop. Yellow
rust (stripe rust), which caused by the fungal pathogen Puccinia striiformis f. sp. tritici is
one of the most significant biotic factors affecting wheat yield and quality. It may cause up
to75 % yield loss in wheat under epidemic conditions in Turkey. Although the disease can
be controlled using fungicides and cultural methods, the resistance breeding is considered
to be the most economical and environmentally appropriate strategy. Use of genetic
resistance and development of resistant cultivars are very important to control the disease.
Izgi-01 is a resistant cultivar to yellow rust and was released for Central Anatolia Region
of Turkey. The objective of the study was to determine the inheritance of resistance in Izgi
2001, a bread wheat cultivar. For this purpose, F 2 seedlings and adult plants of Izgi-01 X
Aytın-98 cross were tested against yellow rust under artificially created disease conditions
using appropriate inoculation methods in the greenhouse and field. The experiment was
conducted at the Research Station of the Central Research Institute for Field Crops in
Yenimahalle and Haymana locations, Ankara, Turkey. For adult plant stage test, the F 2
plants and the parents were sown by hand in 2 m-long rows with 33 cm space between the
rows in October 2008. The F 2 plants for seedling stage test, the parents and the susceptible
checks were sown in small pots and they were kept in the greenhouse until scored in February
2008. As a susceptible check, Little Club, was used for both seedling and adult plant
reaction tests. The yellow rust isolate used for inoculation both seedlings and adult plants was
virulent on Lee, Heines Kolben, Heines Peko, Kalyansona, Sonalika, Avocet R, Federation*4/Kavkaz,
Avocet S and Tres, Express, Lee, Lemhi, Fielder, Yr9, Produra genotypes
in Europe/Australasia and North American differential sets, respectively. As a result, Chi-
Square test showed that the resistance was controlled by at least a dominant gene in İzgi-01
cultivar.
