Evaluation of Wheat Germplasm Against the Cereal Cyst Nematode (Heterodera avenae won.) •

Abstract

The cereal cyst nematode, Heterodera avenae Woll. was proved to be the
causal organism for 'Molya' disease of wheat and barley in Rajasthan (Vasudeva,
1958). Since then this nematode has been reported from all the wheat growing
regions in India including Rajasthan, Punjab, Haryana, Delhi, Himachal Pradesh
and Jammu & Kashmir. Use of resistant cultivars is one of the most effective
and economical ways of reducing this nematode in soil. Resistance in wheat
against H. avenae is known so far only in two cuItivars, namely, 'Loros' from
Denmark (Nielsen, 1966) and 'Katyil' from Australia (Brown and Young, 1982).
