Pollen flow of Brassica napus cultivar and possible breeding with Sinapis arvensis

To evaluate potential hybridization, Brassica napus L. var. oleifera Del. (oil seed-rape) were cropped. B. napus forms spontaneous hybrids with both of its wild progenitor species, B. rapa (wild turnip) and B. oleracea (wild cabbage), and the extent of sexual compatibility between Brassica napus (oilseed rape) and wild Brassica species has been considered. Some wild plant species belonging to Brassicaceae have been selected to evaluate possible hybridization and gene flow. Sinapis arvensis was consider as one possible candidate to hybridize with oilseed rape. Due to the close genomic relationship between these taxa, nSSR primers designed for different Brassica species were tested to amplify both in Brassica napus and Sinapis arvensis. Therefore we looked for S. arvensis populations and oilseed B. napus cultivars which would hybridize in the field.
