Summary: We report a new set of nine primer pairs specifically developed for amplification of Brassica plastid SSR markers. The analysis was generally able to separate plastid types into taxon-specific groups. We interpret our results with respect to taxon differentiation, hybridisation and introgression patterns relating to the ‘Triangle of U’.  Link: http://link.springer.com/article/10.1007%2Fs00122-006-0377-0#page-1
