Germplasm resistant to common root rot was developed from crossing Aegilops ovata with Triticum aestivum, using Chinese Spring ph 1b genetic stock and the cultivar Leader. The germplasm lines had yellow flour pigment and a longer mixing time and lower SDS sedimentation volume, falling number, and mixograph peak height than Leader. Yet, for most agronomic and quality traits, the germplasm was similar to that of Leader and Neepawa. Seed was classed as CWRS. This germplasm represents a different source of genes for resistance to common root rot than currently available in red spring wheat cultivars or breeding lines.
