In this trial 32 bread wheat advanced lines were evaluated along with two check varieties, Parsi and Sivand in 5 stations (Karaj, Kermanshah, Zarghan, Neishabour and Isfahan) of temperate zone. These materials have been advanced through evaluation and screening in preliminary regional wheat yield trial of last crop season of temperate zone. Planting of the experimental plant materials was done in Aban, 1388 (November, 2009) and were looked after during winter. Weed control and field records for disease resistance, lodging, heading and maturity dates, plant height, kernel color, and shattering were done in spring. Finally after harvesting kernel yield was measured Using mean rank and analysis, and considering all recorded traits and also information of disease nurseries, superior genotypes were selected. From 16 evaluated genotypes of first experiment, entries no 4, 8, 9, 10 and from second experiment genotypes no 22, 23, 24, 25, 27, 28, 30, 32, 33, 34, 35 and 36 were selected to be studied in a new stability and adaptation trial in 8 stations of temperate zone during two consecutive crop seasons i.e. 2010-2012.
