Glucosinolate Profile in Different Mediterranean Brassica Species (n=9)

Mediterranean basin represents an important centre of origin and diversificationof Brassicaceae and above all of B. oleracea because are widespread severalBrassica wild species (n=9) which seem support an intense genetic flux among them. Infact, the genetic self-incompatibility system characterize some wild populations ofBrassica (n=9) and B. oleracea landraces and favours the genetic recombination andthe set-up of several forms and types within the same crop, such as in broccoli,cauliflower, kale, etc. That is observed mainly for bio-morphological traits but westarted to study their antioxidant profile. In this frame DISPA of Catania Universityand MBG (CSIC) of Pontevedra, Spain collected Brassica species (n=9) in view todefine their glucosinolate profile. Cluster and principal component analysis wereperformed to determine relationships among accessions and to obtain information onthis material. The dendrogram showed seven groups, one group including most of thepopulations and six small independent groups.
