Cereal cyst nematode ( CCN ) severely threatens wheat production in many regions of China. Cultivars susceptible to are the main reason for its spread. This study was initiated determine whether cultivars conferring different resistance levels dominant determinants populations rhizospheric soil. Field experiments were conducted at two locations Henan province, China, where high Heterodera filipjevi or H. avenae have occurred, during growing seasons 2010/11 and 2011/12. Conventional enumeration white female nematodes on plant roots, reproductive factor Rf a molecular diagnostic approach, PreDicta B test, soil testing service based sensitive quantitative PCR technique, used soils seven common durum with reactions . The resistant responses conferred by Wascana Wakooma Madsen effective against both resulted significantly fewer (<5 females) lower Those limiting propagation, resulting eggs their soils. Taikong 6 moderate (5–10 species. Tianmin 668 only showed Aikang 58 Wenmai 19 species, which facilitated increases populations. These results demonstrate that genotypes obvious impact propagation nematodes.
