53 individual plants representative of the O. latifolia complex of the genus Orzya were analysed for their polyphenolic content. This collection contained diploid and tetraploid types, plants with genomes B, C, D and E, and plants originating from Africa (O. punctata, O. eichingeri), Asia (O. officinalis, O. minuta), America (O. latifolia, O. alta, O. grandiglumis) and Australia (O. australiensis). The diploid species showed homogeneous flavonoid pattern that nevertheless allowed a subtle genomic organization to be discerned. Moreover, for the CC genotypes geographical variation was observed. On the other hand, the tetraploids were characterized by a large diversity of new flavonoid compounds. © 1989.
