Mapping of molecular markers on Brassica B-genome chromosomes added to Brassica napus.
Using interspecific hybridization, B-genome chromosomes from different sources of Brassica (B. nigra (BB, 2n = 18), B. carinata (BBCC, 2n = 34) and B. juncea (AABB, 2n = 36)) were transferred into the Canadian cv. Andor of B. napus. Monosomic addition lines were selected (AACC + 1B, 2n = 39) by cytological control. For characterization of the alien chromosomes, series of isoenzymes, RFLPs and RAPD markers were employed. This permitted the identification of a total of 39 lines representing seven of the eight B-genome chromosomes.
