A study of crown rust resistance in historical and modern oat cultivars representing 120 years of Polish oat breeding

The objective of this paper was to measure resistance to Puccinia coronata f.sp. avenae (Pca) in a set of 63 previously uncharacterised new and historical oat cultivars representing 120 years of Polish oat breeding. The distinctiveness of the obsolete and modern gene pools led to the expectation that the earlier cultivars could be a valuable source of useful resistance genes discarded during subsequent breeding. The plant material was tested at...
