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. | Phenotypic stability for yield and some quality traits in Brassica juncea L.
