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.
