Haydari was developed from the cross between Ghk"s"/Bow"s"//90Zhong87 line and Shiroodi cultivar in Cereals Research Field at Karaj in 1996-97 cropping season. The F1 generation and segregated populations were managed at Karaj from 1997 to 2003. The performance of Haydari was evaluated in breeding nursery trials across all the research stations in cold regions of the country from 2004 to 2008 and in on-farm and verification trials from 2008 to 2014. It expressed grain yield higher than the other genotypes and check cultivars throughout the experiments. High grain yield and tolerance to terminal drought make Haydari well-suited to the cold regions in Iran. The highest grain yield of Haydari was 10600 kg ha-1 under irrigated condition which reported from Hamedan experimental station in 2005-06 cropping season. It displayed resistance to stripe rust and moderate susceptibility to leaf rust and stem rust. Across all experimental sites over two years, the average grain yield of Haydari under optimum irrigation and post-anthesis drought stress conditions was 7.1 and 6.0 t ha-1 compared to 6.4 and 4.5 t ha-1 for Shahryar (check cultivar), respectively. Haydari has exhibited good general baking quality similar to check cultivar Shahryar. It is an awned and facultative in growth habit and its grain is hard and amber. Haydari was registered in 2015 and is appropriate for under optimum irrigation and post-anthesis drought stress conditions in cold regions of Iran.
