Abstract

Ten promising finger millet (Eleusine coracana (L.) Gaertn.) genotypes were evaluated over nine locations for three years 2006, 2007 and 2008. The stability parameters were computed for traits like number of productive tillers and grain yield. The Eberhart and Russell model (1966) was used to study the stability parameters. The pooled two-way analysis of variance revealed that the mean sum of squares (MSS) due to genotype × environment (G × E) interaction was highly significant for both number of productive tillers and grain yield indicating the presence of variability both among the genotypes and environments. Stability of genotypes was predicted on mean yield and the comparative value of stability parameters. Over the years arid locations for number of productive tillers, the genotypes OEB211, VR888, OEB57, PR202, VL333 and HR 374 were specially adapted to favourable environment, whereas, genotypes GPU65 and GPU66 were specially adapted to unfavourable environment. For grain yield, the genotypes VR888, OEB57 and HR374 were specially adapted to favourable environment. In contrast, the genotypes GPU65, GPU66, OEB265, OEB211 and VL333 were specially adapted to unfavourable environment
