Abstract :The present study was conducted to assess green herbage yields of hybrid maize cultivars grown under different environments for two years. GGE biplot analysis method and regression coefficients were used to assess genotype x environment interaction and to identify the most stable cultivars for green herbage yield. Experiments were conducted in six different environments, green herbage yields in the environments varied between 6.0 t da-1 insert ignore into journalissuearticles values(E5); and 10.4 t da-1 insert ignore into journalissuearticles values(E1); and green herbage yield yields of the cultivars varied between 6.8 t da-1 insert ignore into journalissuearticles values(G14); and 10.9 t da-1 insert ignore into journalissuearticles values(G18);. In GGE biplot analysis, the first two principle component insert ignore into journalissuearticles values(PC); axis explained about 82.45% of total variation. The genotypes with high PC1 and low PC2 values and regression coefficient of 1.0 were assessed as stable. The cultivar Safak insert ignore into journalissuearticles values(G18); with such values was identified as the most stable cultivar. The regression coefficient of 1.0 and the greatest green herbage yield proved the stability of that cultivar. The cultivars with higher PC1 and lower PC2 values [30B74 insert ignore into journalissuearticles values(G2);, Seme Kukuruza 877 insert ignore into journalissuearticles values(G22);, ADV 2898 insert ignore into journalissuearticles values(G24);, Wayne insert ignore into journalissuearticles values(G17);, and Safak insert ignore into journalissuearticles values(G18);] generally had higher green herbage yield than the general average. Safak insert ignore into journalissuearticles values(G18);, 30B74 insert ignore into journalissuearticles values(G2);, Seme Kukuruza 877 insert ignore into journalissuearticles values(G22);, ADV 2898 insert ignore into journalissuearticles values(G24); and Wayne insert ignore into journalissuearticles values(G17); cultivars can be use green herbage yield production in south eastern Anatolia will allow the growers to have a profitable production.
