Abstract
Seedling resistance of 46 bread wheat and 14 durum wheat cultivars grown commonly in Turkey to stem rust races TTTTF, RTTTC, and RTTTF, the most common races in the Kastamonu region of Turkey, was determined under greenhouse conditions. Bread wheat cultivars Tahirova 2000, Yıldırım, Alpu 2001, Canik 2003 and Basri Bey 95 were found to be resistant to three stem rust races. Durum wheat cultivars Sarı Çanak 98 and Fırat 93 were resistant to stem rust race TTTTF. Durum wheat cultivars Eminbey, Altıntaş 95, Zühre and Sarı Çanak 98 were resistant to stem rust race RTTTC whereas durum wheat cultivars Eminbey, Altıntaş 95, İmren, Yelken 2000 and Zühre exhibited resistant reaction to stem rust race RTTTF. The majority of the wheat cultivars tested showed susceptible reactions to these stem rust races.
Highlights
Çanak 98 and Fırat 93 were resistant to stem rust race TTTTF
Stem rust races RTTTC and RTTTF have been reported from Kastamonu, Turkey (Mert et al 2012a), previously and stem rust races TTTTF and RTTTF have been reported from Sinop, Turkey (Akci & Karakaya 2019, 2021b)
Seedling reactions of 46 bread wheat and 14 durum wheat cultivars to stem rust races TTTTF, RTTTC, RTTTF were determined under greenhouse conditions
Summary
Çanak 98 and Fırat 93 were resistant to stem rust race TTTTF. Durum wheat cultivars Eminbey, Altıntaş 95, Zühre and Sarı Çanak 98 were resistant to stem rust race RTTTC whereas durum wheat cultivars Eminbey, Altıntaş 95, İmren, Yelken 2000 and Zühre exhibited resistant reaction to stem rust race RTTTF. Using the races TKTTC, RTKTF, and RTTTC, the seedling response of 97 bread wheat and 41 durum wheat cultivars were determined (Mert 2010). In a study conducted in Kastamonu, Turkey, stem rust races TTTTF, RTTTC and RTTTF were found as the most common races (Akci and Karakaya 2021a). Stem rust races RTTTC and RTTTF have been reported from Kastamonu, Turkey (Mert et al 2012a), previously and stem rust races TTTTF and RTTTF have been reported from Sinop, Turkey (Akci & Karakaya 2019, 2021b) In this current study, under greenhouse conditions, the seedling response of 60 Turkish bread and durum wheat cultivars to these races was determined. The reactions of Turkish bread and durum wheat cultivars to stem rust races TTTTF and RTTTF were not determined previously
