The objective of these studies was to find variety, which produce higher yield than local checks with high adaptability. This research envolved two experiments which experimental materials comprised 10 and 8 lines along with local checks in RCBD with four replications at Kermanshah, Lorestan, Ilam, Gachsaran, Gonbad, Shirvan and Gazvin Research Stations during three years ( 2001-04). Combined analysis was done for each station and all of the stations. Stability analysis was done by simultaneous selection for yield and stability, and Rank method. 1-The results of combined analysis of first experment (11 varieties) showed that year × location, genotypes × location and year × location × genotypes were significant at 1% level of probability. There was not significant difference among the genotypes yield. The result of Duncan,s Multiple Range Test showed that FLIP 92-12L with productivity 1263 kg/ha had significantly higher yield than local check at 5% level of probability. Results of stability analysis on grain yield using simultaneous selection for yield and stability and Rank method showed that FLIP 92-12L the most stable genotypes. 2- The results of combined analysis of second experment (9 varieties) showed that year × location , genotypes × location and year × location × genotypes were significant at 1% level of probability. The results of combined analysis showed that there was not significant difference between yield of genotypes. The result of Duncan,s Multiple Range Test showed that there was no significant difference among yield of genotypes. Cabralinta produced the highest yield with 927 kg/ha. Results of stability analysis on grain yield using simultaneous selection for yield and stability and Rank method showed that stablity of ILL 857 was suitable than other lines.
