The experiments were established in randomized completely block design with four replicates. Four triticale varieties (Tatlıcak 97, Melez-2001, Presto, MİKHAM-2002) and one line (Line 1, candidate to registration) test materials were used in the study. The objective was to determine genotype x environment relationship in the context of change towards the environment. According to the result of stability parameters, Presto was the most stable variety in un-favorable conditions, while Line 1 was the most stable variety in favorable conditions. The average grain yield per unit area of the all varieties under different conditions was changed between 368.1-429.2 kg/da.
