Brassica juncea (2n=36) is an amphidiploid species derived from inter specific cross between Brassica nigra (2n=18) and B. rapa (2n=20). B. juncea is used as sources of oil, vegetable, condiments and fodder and act as laxative, stimulant to gastric mucosa and increase intestinal secretion. Mustard oil was once considered to be unsuitable for human consumption due to high content of erucic acid. Early maturing, high yielding Australian canola quality brassica juncea lines have been developed and are currently being crossed with higher oleic acid sources. In brassica juncea the most quality to be considered are erucic content, low glucosinate content, high fatty acid accumulation, and productivity per unit area flavonoids, resistance disease and essential oil. Economically important traits were transferred through hybridization aided with embryo rescue; double low, high oil content, shattering tolerance in B. napus, and low erucic/high oleic acid, yellow seed coat color, double low, and resistance/ tolerance to fungal diseases, Albugo candida and Alternaria brassicae in B. juncea. Therefore to boost quality and quality traits in Brassica Juncea, heterosis breeding is appropriate method.
