Cereal Root Eelworm (Heterodera Avenae Woll.) and Spring Barley Varieties

Cereal Root Eelworm (Heterodera Avenae Woll.) and Spring Barley Varieties CEREAL ROOT EELWORM (HETERODERA AVENAE WOLL.) AND SPRING BARLEY VARIETIES BY R. GAIR National Agricultural Advisory Service, Shardlow Hall, Derby T. J. A. PRICE Gleadthorpe Experimental Husbandry Farm, Nr. Mansfield, Notts. AND W. E. H. FIDDIAN National Institute of Agricultural Botany, Cambridge, England Field trials in the East Midland counties of England in 1956-60 demonstrated marked differences in the rate of build-up of Heterodera avenae populations between different spring barley varieties. Those at present in commercial use, and several about to be introduced, were found susceptible to injury by the pest and their yields suffered. The Danish variety Kron was partially resistant, producing higher yields and fewer cysts on infested land but gave lower yields on uninfested land. Another Danish selection, No. 191, was resistant to two British populations of the eelworm. Cereal root eelworm is widely distributed throughout England and Wales where its damage is most common on light soils (Southey, 1955, 1956). Most attention has been paid to its effect upon oats, because they are most seriously affected (Hesling, 1957). The national acreage of oats has recently declined and their place has been partly taken by spring barley.
