GENOTYPE X ENVIRONMENT INTERACTION AND STABILITYANALYSIS OF LOWLAND RICE GENOTYPES

Twenty-one lowland rice genotypes were evaluated for theirstability parameters with respect to grain yield in a multi-locational trial at fivedifferent 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 reflectsexistence of genotype x environment interactions and contribution of both linearand non-linear components to genotype x environment interactions. throughstability 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-4were suitable for better environments. psr 1209-2-3-2, cr 780-1937, ambika, or877-st-4-2, ndr 40055-2-1 and cr 662-2211 were identified for poorenvironments.
