Correlations were worked out between yield and yield contributing characters of Brassica juncea at the phenotypic, genotypic and environmental levels. Yield was highly associated with number of pods per plant, number of secondary branches and number of primary branches. The genotypic correlations were generally lower. Most of the phenotypic and environmental correlations between the yield attributing characters themselves are significant.
