Five short duration rice genotypes viz. ADT 36, ADT 41, ADT 42, IR 72 and AD 85361 were studied for stability performance under three nutrio-environments viz, O (E1). 100 kg N ha (E2) and 200 kg N ha' (E) for 18 characters, G x E interaction was significant for four characters only viz, spikelets panicle, grains panicle", 100-grain weight and grain yield ha". Genotypes ADT 36 and AD 85361 were the most stable and consistent ones for the traits studied in all environments.
Keywords: Genotype, nutrio-environments, stability, regression
