Development of novel yellow-seeded Brassica napus germplasm through interspecific Cross B . juncea × B . napus 1 ( G 3 )

The yellow seeded trait is a challenge of the rapeseed breeding at present because of lack of yellow-seeded germplasm in Brassica napus. The yellow-seeded B. juncea landrace Sichuan Yellow as the gene donor was crossed with the double-low B. napus cultivar and the yellow-seeded plants were found in the BC1F2 population. The novel yellow-seeded B. napus lines with over 46% oil content have been developed after successive selfing of four generations.
