Abstract: Orobanche Cumana is an important influence factor in sunflower production . It is very severe in Wulateqianqi, Inner Mongolia and Aletai, Xinjiang. In this study, in natural infested fields we screened the resistance of 56 varieties in Xiniang in 2012, 22 varieties in 2013 and 20 varieties in 2014 in Inner Mongolia. The result showed that among 22 oil sunflower in Xinjiang, 16 showed immune to broomrape (Longkuiza 1, F08-1, LiaofengF53, ChiCY101, S26, MGS, S31 etc. ) , among 34 confection sunflower varieties , JK106 showed immune. In Inner Mongolia among oil sunflower varieties ChiCY102 , F08-1 showed immune , MSG、Xinkuiza5、Chi029×115R、Chi128A×116R highly resistant. Among 18 confection sunflower varieties, JK106 and JK103 were resistant, the others are susceptible or highly susceptible to broomrape. The oil sunflower CY102 was immune to broomrape in 2 place. Through this identification, we found that the race of Orobanche Cumana in Inner Mongolia was higher than that in Xinjiang, and oil sunflower showed more resistant than confection sunflower.
