The current investigation aims to determine the phenotypic stability and GxE interaction among the Brassica juncea L. genotypes. Fifteen released genotypes of Brassica juncea L. were evaluated in two different environments and two dates of sowing during Rabi 2014-2015 and 2015-2016. Analysis of variance indicated that all the genotypes exhibited significant genetic differences except forno. of secondary branches/plant, siliqua length, 1000 seed weight and oil content. The mean squares due to environment were significant for all the characters and GxE interactions were also observed to be significant for traits viz., no. of primary branches/plant, no. of secondary branches/plant, days to 50% flowering, days to 100% flowering and days to maturity. Considering high mean performance, unit regression and non-significant mean square deviations, the genotypes DRMRIJ-31 and Varuna are stable and suitable for high performance environment. The genotype PM-21 was considered as stable and suitable for low performance environment.
