Genotype x environment interaction was studied for grain yield in 24 genotypes of lowland rice under five different environments in eastern India. Significant genotype (G) and environment (E) interaction was observed. Both linear and non-linear components of G x E interaction were significant, linear component being the predominant. On the basis of stability parameters two genotypes, RAU 79-2-14 and RAU 617-59-14-1 were found to be most stable with high grain yield over different environments. The selection from Raipur (IET6286/Bd.83)-29 was identified as suitable genotype for favourable environments.
