Seventy five crosses of Indian mustard [Brassica juncea (L.) Czern & Coss] generated by crossing of fifty lines with five testers in a line x tester mating design, which were used to estimate the standard heterosis potentiality for seed yield, its component traits and oil content. These parents, crosses and checks were sown in randomized complete block design under four environments each replicated thrice at two different locations. Observations were recorded on thirteen different characters. Standard heterosis was estimated on the basis of best check PUSA BOLD for these characters based on the pooled data over environments.
