In this trial 16 genotypes were evaluated along with two check cultivars Rakhshan and Baharan, and two promising lines M-93-11 and M-94-14 (released as Amin) totally 20 genotypes in a RCBD experiment with 3 replications in 8 experimental stations of temperate zone during two cropping seasons 2018-2020. These genotypes had been selected and advanced through evaluation and screening in advance regional wheat yield trial of 2017-2018 cropping season in temperate zone. Planting of the experiments was done in November of each cropping season and were looked after during winter. Weed control and field records for disease resistance, lodging, heading and maturity dates, plant height, and kernel color were done in spring. Irrigation management of the experiment was cutting of irrigation at the stage of heading onward in 3 stations: Isfahan, Neishabour and Varamin. Other stations experiment was well watered. Finally, after harvesting, grain yield was recorded. Second year data of Broujerd due to late harvesting was not accessed on time and hence two years data of this station ignored from ANOVA. Still first year data of Broujerd was used in Ranking analysis. Combined ANOVA for 7 stations for two years was performed. Effect of year × location× genotype, year × location , location and genotype were significant, but other important effects were not significant. To evaluate stability and adaptation of investigated genotypes non parametric ranking analysis and also superiority index (Pi) was used. Considering performed analyses and all recorded traits and also information of disease nurseries superior genotypes were selected. Based on the results entries M-97-11, M-97-12, M-97-18 and M-97-20 were superior genotypes and considered for seed multiplication and further screening. Finally, maximum 3 best performers will be considered for farmer field trials.Key Words: Adaptation, Stability, Bread wheat, Yield trial, Temperate zone
