Abstract:
The aim of this study was to determine the genotype-environment (GE) interaction and also to determine stable corn cultivar for grain yield in Turkey. The study was carried out from 2 years and 3 different locations around the Central and South Anatolia Region. GE interaction was analyzed by linear regression techniques. Stability was estimated by the Eberhart and Russell methods. According to the stability analysis, it’s seen that the cultivar 3 was the most stable for grain yielding. Among the cultivars, the highest grain yield was obtained from cultivar 3 (9.4 t ha-1) at across environments. This genotype had regression coefficient ( =1) around unity and deviations from regression values ( =0) around zero; considering that they are responsive to environment changes and they can be recommended for favorable environments.
