Fourteen chickpea varieties were grown in four locations (Tokat-Tahtoba, Tokat-Pazar, Tokat-Zile and Amasya-Gökhöyük) in 2001 and 2002 in order to determine their genotype by environment interactions. Trials were conducted in Completely Randomized Block Design with four replications. Seed yield per decare trait was studied. Location x variety interaction was significant at 1% of probability for seed yield. Seed yield, the most important trait, varied from 81.9 to 191.9 kg per decare. Of the locations, 2002-Tahtoba had the highest yield while 2002-Zile the lowest. Seed yield of the varieties varied from 94.9 to 153.1 kg/da. Akçin-91 had the highest but Uzunlu-99 and Küsmen-99 the lowest seed yield. When adaptation classes of the varieties were considered, Menemen-92, Aziziye-94, Sarı-98, Sıra Nohut and Konya had moderate adaptation to all environments, Akçin-91 had good adaptation to all environments, İspanyol had moderate adaptation to good environments, Er-99 and Gökçe had good adaptation to good environments, Aydin-92, Damla-89 and İzmir-92 had moderate adaptation to poor environments, and Uzunlu-99 and Küsmen-99 had poor adaptation to poor environments. According to yield stability parameters, Menemen-92 and Aziziye-94 were the most stable varieties.
