| 520 | _aMaize genotypes vary in their response to variable environmental conditions. Twenty genotypes were tested at nine locations in Ethiopia ( 1,100-2,240 masl) in the 1998 cropping season to study their phenotypic yield stability .Analysis of variance and stability analysis were computed. Variances due to genotypes, environments, and G x E interaction were significant. Linear and non-linear components of G x E interactions were also present. Most genotypes had significant deviation mean square (S2di) implying that they were unstable. None of the top yielding genotypes exhibited general adaptability. Some genotypes had relatively good performance in mid and high altitude areas whereas some had good performance in mid and low altitude areas indicating the possibility to develop specific genotypes adapted to mid and high or low and mid altitude areas. However, the top yielding genotypes were specifically adapted indicating that for high yield potential in each mega-environment, a specific breeding programmme is necessary. Results also showed that understanding of the biophysical limitations within the mega-environment will pave the way for genetic improvement for these limitations. | ||
