Receiving high and stable grain yield at different environments is one of the aims in cereal breeding programs. In order to compare results of research under on-farm conditions, it is necessary to carry out research-extension project to receive high grain yield and adaptability lines. In this project, EWYT-C-91-4 with pedigree "Zm/Shiroodi/6/Zm/ 5/Omid/4/Bb/Kal//Ald/3/Y50E/Kal*3//…" as promising line and Haydari "Ghk"s"/Bow"s"//90Zhong87/3/Shiroodi" as control and commercial cultivar were sowed under irrigated and on farm conditions in Nagadeh and Miandoab Regions, North West of Iran. The planted area per location for each genotype was 5000 m2. Land preparation and sowing were accomplished according to on-farm conditions of the region. Seed rate was based on 1000-kernal weight (450 seed/m2) and fertilizer applications was done based on recommendations from soil tests. Results analysis using Hotellings T2 test showed significant differences for nine characteristics. In addition, t-student mean comparison revealed that EWYT-C-91-4 line was superior to the control cultivar. This line had the lowest coefficient and range of variations, and standard deviations within two regions. Combined analyses of variance showed significant differences within locations. Finally, EWYT-C-91-4 due to more grain yield, total dry matter and diseases resistance could replace commercial cultivar. One thousand spikes of EWYT-C-91-4 promising line was provided for producing breeder seed.
