Thirteen autumn rice genotypes were evaluated in three environments under rainfed and direct seeded conditions. Both linear and nonlinear components of G x E interaction were significant for productive tillers/m2 and grains per panicle, while only linear component was significant for grain yield. Under medium yielding environment suitable genotypes were China, Tulashi, Annada and Culture 1 for grain yield; IET 10898, IET 10895, Tulashi, Annada and CR 635-49 for productive tillers/m2, and China and Annada for grains per panicle. Rangadoria, a local genotype, was suitable for grain yield under low yielding environment.
