Maize is an important crop in Rwanda, ranking sixth among food crops (FRSP and DSA 2002). However, maize yields are very low and one way to increase productivity is to release improved varieties. The release of maize varieties requires testing across seasons and sites and on-farm trials.,Yield stability is an important factor to consider when releasing a cultivar. The method used to analyze yield stability was developed by Eberhart and Russell (1966). It involves regressing the genotype mean from several locations on the environmental value (environmental index). A stable genotype has a regression coeffident close to one and a deviation from regression close to zero. Stable varieties are easily adopted by farmers.
