  1. n a = observed number of alleles; n e = effective number of alleles [51]; H O = observed heterozygosity; H E = Nei's [40] unbiased expected heterozygosity; Inor = normalized Shannon's Index [41, 42]. For feral populations all statistics are given both, considering only the eight populations (64 individuals) or, in brackets, also including the 13 single individuals (77 individuals). For characteristics of the nine B. napus SSR-loci used see Lowe et al. [38]. The primer sequences are listed in BrassicaDB http://ukcrop.net.
