✦ Synopsis

By using 15 available mono/nullisomic lines of Sun II background, the Heterodera avenae resistance genes in Nelson (from Avena sativa CI 3444) and Panema (from A. sterilis I. 376) were located on monosome XV. Genes with smaller effects were located on monosomes VIII and X. The absence of these genes derived from Sun II would increase cyst production on plants lacking major resistance genes.

Methods

The mono/nullisomic lines were used as maternal parents and each was crossed with Nelson and Panema. The aneuploid condition of the mono/nullisomic was ascertained
