The study on agronomic characteristics and grain yield of winter and facultative bread wheat genotypes in yield trial in cold and moderate-cold dryland areas about 2683 advanced winter and facultative genotypes in different environment conditions of I.R.Iran were evaluated ( in 8 locations: Maragheh, Sararood, Qamloo, Ardebil, Shirvan, Zanjan, Ilam, and Ouromieh) in the 2002-2003 crop season. In the observation nuerseries (PBWYT and WON) used unreplicated, and the best genotypes selected based on agronomic characteristics and grain yield with compear of checks, but in the yield trial experiments, Simple analysis of variance on grain yield of each experiment showed that significant differences among the genotypes. According to the classification of the genotypes based on the mean of grain yield and agronomic characteristics, from 1235 variety and lines about 110 high yield, earliness genotypes were selected in the Maragheh research station, and in the other research stations, overall based on the mean of grain yield and diseases results about 15 to 25 % of best genotypes were selected for study in the next crop season in advanced trials. Based on yield and genetic resistance to biotic and abiotic stresses in the cold and areas Dryland Areas of Iran, 13 advanced bread wheat lines choosed for moderate-cold study in the stability and adaptability experimental in the cold and moderate-cold of dryland areas of Iran.
