ABSTRACT
The sunflower is one of the most important oil crops. Orobanche cumana is a holoparasite, that infests sunflower plants. We have provided RAPD analysis of six sunflower lines, two of which are susceptible, and four are resistant to broomrape. Our results showed a polymorphism between susceptible and resistant sunflower lines in RAPD patterns generated with eight of totally seventy primers used.
