AbstractEvaluates inherited traits of the Helianthus annuus texanus, a stabilized hybrid of Helianthus annuus and H. debilis. Helianthus debilis has greater resistance to insect damage than H. annuus. Three of seven damage traits were significantly different in the hybrid compared with H. annuus. This suggest that the incorporation of resistance traits from H. debilis was important in the adaptation of H. annuus to central and southern Texas.
