A yellow‐seeded exotic accession of Brassica juncea has shown complete freedom from white rust and powdery mildew and a high degree of resistance to Alternaria black spot under conditions of heavy disease infestation in the field. The germplasm line was, however, too late in flowering and maturity to be useful for either processing directly into a variety or to be involved in a crossing programme for breeding. Somaclonal variation from this accession has provided a highly productive line which retains the resistance to diseases of the parental material.
