Abstract: 

TEN Families of Maize from European origin were been evaluated in five environmental sites belonging to the General Authority for Scientific Agricultural Research (Qarhata, Tartous, Homs, Hama, and Lattakia) during 2014 season. to study The genetic-environmental interaction and yield stability analysis Using several statistical methods which are: Eberhart and Russell method it measures The sensitive of genotypes and their affected to genetic-environmental interactions, Perkins and Jinks method which is a modified method from the first method, Wricke & Weber which depending on Shukla coefficient, Pinthus method which depends on Determination coefficient (R²) , and Francis method which depends coefficients of variation (cv%). The experiment was carried out according in randomized complete block design, with three replicates. The results showed According to the least significant difference at the 5% level That Homs and Qarhata was significant, and the families (Sh5،Sh7) More fastness and stable compared to other families, while the families (Sh1، Sh2) were sensitive to environmental changes, and the families (Sh8، Sh9،Sh10) were vulnerability to environmental changes and low adaptation to stressful environments.

Key words: Zea mays, Genotype × Environment Interactions, Yield Stability.
