In order to study of stability of superior triticale lines, this investigation were conducted in Torogh, Neishabour and Birjand agricultural research stations (Khorasan-e Razavi Agricultural and Natural Resources Research center, KANRRC) in two growing seasons 1385-87 (2006-08). This study were assigned in one ERTYT experiments using Randomized Complete Block Design (RCBD) with 3 replications. Each experiment consist with 18 lines and cultivars of triticale in addition of two checks of triticale: Juanillo 92 and ET-79-17 total 20 entry. These materials selected from ARTYT of last year of Torogh and Birjand stations. During growth and development stages, agronomical traits were recoded. After harvesting, simple and multiple analysis of variance and Rank analysis were carried out. Results of combined analysis showed that the main effects of location (L), year (Y), genotype (G) and interaction effect between location and year (L*Y) were significant with (P0,01). There was an significant differences (P0,05) for interaction effect between location, year and genotype (L*Y*G). The mean grain yield of 3 lines ET-85-17, ET-85-4 and ET-85-20 were 7283, 7014 and 6939 kg/ha. So these lines had the higher grain yield in comparison with the check (Juanillo 92). The mean grain yield of these 3 promising lines were about 25,4٪, 20,7٪and 19,5 ٪higher than in comparison with triticale check (Juanillo 92), respectively. Results of rank analysis showed that these 3 promising lines had beter mean of rank and yield stability in the other entries. Therefore, based on superiority of grain yield, yield stability and suitable agronomic traits, these 3 promising lines engaged for on-farm researches, realizing and nomenclature
