Twenty-one lowland rice genotypes were evaluated for their stability
parameters with respect to grain yield in a multi-locational trial at five
different sites of Eastern India viz. Central Rice Research Institute,
Cuttack (Orissa); OUAT, Bhubaneswar (Orissa); CRS, Masodha (UP); RAU, Pusa
(Bihar) and RARS, North Lakhimpur (Assam). Pooled analysis of variance
reflects existence of genotype x environment interactions and contribution of
both linear and non-linear components to genotype x environment interactions.
Through stability parameter analysis, it was found that Rayda B3, CR 778-95
and CR 661- 236 were suitable for all environments. The genotypes Sabita and
OR 1358-RGA-4 were suitable for better environments. PSR 1209-2-3-2, CR
780-1937, Ambika, OR 877-ST-4-2, NDR 40055-2-1 and CR 662-2211 were
identified for poor environments.
