GXE INTERACTION IN SHORT DURATION RICE

Abstract

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
