Abstract EN
This study aimed to investigate the performance and stability across eleven locations i.e.
Behira (Env1), Kafr El Sheikh (Env2), Dakahlia (Env3), Gharbya (Env4), Monofia (Env5), Sharkia (Env6), Giza (Env7), Beni Suief (Env8), Menia (Env9), Assiut (Env10), and Sohag (Env11) of 7 genotypes of maize and two commercial check hybrids (SC-162 and SC-168) during 2015 summer season.
A randomized complete block design with 6 replications was used at each environment.
Significant differences among genotypes, environments and genotype X environment interaction for grain yield were detected, Eberhart and Russell, (1966) model was used to estimate different stability parameters.
A large portion of this interaction was accounted by linear regression on the environmental means.
Genotypes x Environments (linear) component was not significant indicating equal importance of both predictable and un predictable interaction in these materials.
All hybrids exhibited significant linear response to environmental conditions.
Coeffecient of deterrmination (R2) ranged from 0.601 to 0.972 for grain yield suggesting that a large portion of variation was existed.
Genotyp 7 and SC-168 would be the most stable genotypes across locations with respect to grain yield.
