A marigold plant, a regenerable portion thereof and seed are disclosed whose flower petals, leaves or flower petals and leaves contain one or more of an enhanced zeaxanthin ratio, an enhanced neoxanthin plus violaxanthin ratio, an enhanced .beta.-carotene ratio, an enhanced .alpha.-cryptoxanthin ratio, an enhanced phytoene ratio or an enhanced phytofluene ratio relative to that ratio in a non-mutant marigold. The flower petals of such a plant also typically contain zeta-carotene that is not normally found in such petals. Also disclosed are methods of preparing such plants, oleoresins and comestible materials that have such carotenoid ratios.

L'invention concerne une plante d'oeillet d'Inde, une partie de cette plante pouvant être régénérée, ainsi que des graines de cette plante. Les pétales et/ou les feuilles de cette plante renferment des teneurs en zeaxanthine, en neoxanthine et violaxanthine, en bêta-carotène, en alpha-cryptoxanthine, en phytoene ou en phytofluène supérieures à celles rencontrées dans une plante d'oeillet non mutante. Les pétales des fleurs de cette plante renferment également du zêta-carotène, ce qui n'est pas normalement le cas dans ces pétales. L'invention concerne également des procédés destinés à la préparation de ces plantes, ainsi que des oléorésines et des produits comestibles renfermant ces teneurs en caroténoïdes.
