Twenty popular rice varieties of Eastern India(110-135 days duration) were evaluated to study the genotype x environment(GXE) interaction and stability nature of different yield traits. The characters like plant height, Ear Bearing Tillers(EBT)/hill, panicle length, Days to fifty percent flowering and Grain yield were recorded in randomly selected plants for four different environments. It is revealed from the study that the varieties viz. Lalat and Saket-4 and PR-113 are stable across the environment for EBT/hill. The variety Daya is stable across the environment for panicle length. IR-72 is stable across the environment for days to fifty percentage flowering. For grain yield, Gouri, IR-8, Jaya and IR-36 exhibited higher yield than population mean with regression coefficient near unity and negligible deviation. Hence these varieties can perform better in all types of environment.
