Genotype-environment interaction for green fodder yield in oats were studied by growing 10 genotypes in four different years. Genotype-environment interactions were present; a large portion of these interactions was accounted for by the linear regression on the environmental means. Although non-linear component was also significant, its magnitude was considerably smaller than that of the linear component. Genotypes 37/14, 5/104, Mulga and Fulgham were found to be most stable and thus their response to changes in environment could be predicted. Fulgham and 5/104 had not only shown linear response and high mean performance over all environments, but also showed better pheno-typic stability. Mulga was found to be a stable variety, suitable for poor environmental conditions.
