Seven broomrape (Orobanche)-resistant CMS sunflower (Helianthus annuus) lines derived from HA89 were crossed with 2 restorers (0536R and 3510R) and F1 hybrids were evaluated for achene yield, oil content, days to flowering, days to maturity, plant height and 100-achene weight during 1992. General and specific combining ability effects were estimated for the 6 traits, most of which were improved in hybrid combinations compared with the background line HA89.
