Technical Abstract: Vernonia (vernonia galamensis) is a potential new oilseed crop high in epoxy fatty acids. One limiting factor to production in the U.S. is the lack of day neutral lines. Hybrids have been made between short day lines and a day neutral line (A0399) at the U.S. Water Conservation Laboratory. Nine populations from these crosses and the A0399 parent were evaluated during 1994 at five locations in replicated field trials. The nine populations were GA25-11, 14D-2-5, 15D-10-12, 29E-OR2-14, 35A-2-9, 35A-2-10, 48A-10, 66L-1-9, and 72A-1-2. The five locations were Phoenix, Arizona; Petersburg, Virginia; Fort Stockton, Texas; Columbia, Missouri; and Medford, Oregon. Lines were evaluated for flowering characteristics, plant heights, total seed yield, grams per 1000 seed, and total oil content. Results indicate that high yielding lines with day neutral flowering and other desirable characteristics can be obtained through crossing and selection in a breeding program.
