Summary
Three interspecific crosses made between Brassica juncea and Brassica napus revealed digenic control with epistatic interaction for white rust resistance trait. The investigation also indicated a close association of parental species type and different grades of leaf waxiness with white rust resistance. It is possible to recover waxy or medium waxy juncea types with white rust resistance, though in low frequency. Treatment of hybrid seeds with EDTA and low doses of gamma-rays seem to have little effect on shuffeling of genomes and genes.
