  1. a Chromosome of B. rapa (A-genome) or B. oleracea (C-genome).
  2. b Not determined.
  3. c The number of unique blocks in a given B. napus LG. The conserved blocks were named according to Schranz et al.[5] and identified by the method described by Parkin et al.[30]. A conserved block contained a minimum of three mapped SSR loci with at least two homologous loci from one of the 24 defined Arabidopsis bocks [5] every 10 cM in B. napus genetic map.
