Abstract:
1. A poppy plant of Papaver somniferum having a stably heritable thebaine-only chemotype which plant upon the harvesting of its poppy capsules will yield a poppy straw having thebaine constituting about 95% by weight or greater of an alkaloid combination, and having oripavine constituting about 5% by weight or less of the alkaloid combination, wherein the alkaloid combination comprises morphine, codeine, thebaine and oripavine; and wherein thebaine constitutes about 3.0% or greater of the poppy straw on a dry weight basis, wherein the thebaine-only chemotype is provided by two independent genes, the first preventing thebaine being converted to neopinone, and preventing oripavine being converted into morphinone, and the second blocking the pathway between thebaine and oripavine.
