The genetics of resistance of common vetch ( Vicia sativa L.) to broomrape ( Orobanche crenata Forsk.) was studied for two years by using the P 1 , P 2 , F 1 , BC 1 , BC 2 , F 2 F 3 , and F 4 generations obtained from crosses between resistant and susceptible lines. Resistant lines were selected by screening a world collection m a naturally infested plot. Resistance was tested both under field and greenhouse conditions. The best index to measure resistance was the number of emerged broomrapes per host plant. The results fit the additive‐dominance model. The main component of the variation was additivity; dominance and interaction effects seemed to depend on the environment. When dominance is expressed, a low number is dominant over a high number of broomrapes per host plant.
