Rust diseases are among the most important biotic stress factors limiting wheat production in Turkey. Stem rust caused by <em>Puccinia graminis </em>f. sp <em>. tritici </em>affects wheat in high altitude areas where plant growth period is long. It was also reported from transitional zones and coastal areas of Turkey. The disease causes significant yield and quality losses of grain and straw under epidemic conditions. One of the most important control method of the disease is development and usage of resistant varieties. Determination of the reactions of resistant varieties against different races of stem rust fungus is important. In this study, the OBVD (Common Wheat Yield Trial) set which includes cultivars and advanced lines developed by agricultural research institutes governed by the General Directorate of Agricultural Research and Policy was tested against stem rust races in the seedling stage in 2009. There are 28 bread wheat genotypes and 10 durum wheat genotypes in this set. Each genotype was planted to 150ml pots and 7 seeds were planted to every pot. The wheat cultivar Little Club was used as the susceptible control. Inocula which belong to races TKTTC, RTKTF, and RTTTC were used in the resistance tests. These races were identified in Turkey previously and they were named based on North American nomenclature system. Three genotypes (1 bread and 2 durum wheat genotypes) were found as resistant while 23 genotypes were found as susceptible to these stem rust races. The other twelve genotypes had different reactions to three different races. Preliminary information related to resistance genes in resistant genotypes was also obtained.}, number={3}, publisher={TARIM VE ORMAN BAKANLIĞI EĞİTİM VE YAYIN DAİRESİ BAŞKANLIĞI}
