%X Fourteen genotypes were tested at five locations in North-Karnataka in the kharif season-2008 to study their yield stability.Pooled analysis of variance and stability analysis were performed. The genotypic (G) x environment (E) interaction and bothvariance due to genotypes and environment were significant. The partioning of G x E interaction into linear and non-linearcomponents indicated that both predictable and unpredictable components shared the interaction. On the basis of stabilityparameters, the top yielding genotypes such as DGGV-2 (964 Kg/ha) DLGG-22 (945 Kg/ha) and DGGS-16 (933 Kg/ha) exhibitthe stable performance across the environments. The genotypes BGS-9 (933 Kg/ha), BPMR-1 (903 Kg/ha) and KGS-83 (908Kg/ha) gave higher yield across the locations but their performance was unstable due to significant deviation from regression. Onthe basis of results, DGGV-2, DLGG-22 and DGGS-16 were the most suitable and desirable genotypes which showed higherstable grain yields at different agro-climatic regions.
