Interpretive Summary: Vernonia contains a novel, epoxidized oil that is useful in coating and paints and is native to equatorial Africa. However, the crop can not be produced in the continental U.S. because when it would normally be grown during the summer, the long days prevent the day-length sensitive plants from flowering. We developed hybrid plants with day neutral flowering that now allow this crop to be grown and flower under conditions such as those in the U.S. These hybrids should benefit producers interested in vernonia for emerging industrial markets, growers, new crop entrepreneurs, and extension agents and researchers.

Technical Abstract: Three vernonia (Vernonia galamensis [Cass.] Less., Asteraceae) hybrids WCL-VP1, WCL-VP2, and WCL-VP3 were released jointly by the USDA-ARS, U.S. Arid Land Agricultural Research Center, Maricopa AZ, and The University of Arizona, Agricultural Experiment Station, Tucson, AZ in 2005. These releases were selected for flowering and seed yield under long day conditions and possess crop maturity intervals that make them suitable for production in the continental U.S.
