Performance of cereal varieties against cereal cyst nematode (Heterodera avenae)
Pakistan Journal of Nematology 38 (2), 149-155
Abstract: The soilborne pathogen cereal cyst nematode (CCN) Heterodera avenae is one of the biotic stress factors that directly affects the crop physiology from seed germination to crop maturity and limits the cereal production in different agro-ecologies of the world. In China, this pathogen is widespread in more than 20 provinces and infects the major cereal varieties and germplasm being adopted for cereal crop production annually. We tested number of cereal accessions to see the host pathogen interaction; among 15 wheat lines from Zhonnguyuan Sun (CAAS) CIMMYT Beijing and 10 lines of oats from Jilin Province were screened against H. avenae. The results showed that 5 wheat and 7 oat lines ranked as resistant genotypes while 9 wheat and 3 oat lines were ranked as moderately resistant and 1 wheat line and the local check were highly susceptible to H. avenae. These genotypes need to be exploited in breeding program to introduce the resistance gene pool in local cereal cultivars for resistance to H. avenae in China.
