Field trial evaluations conducted in Eastern Washington revealed shifts in grain yield rankings among spring wheat and spring barley cultivars under severe pressure from Rhizoctonia root rot, depending on location and management system, suggesting that different levels of avoidance, escape, recovery from, or tolerance to Rhizoctonia root rot may exist among spring cereal cultivars (Kidwell et al.
The objectives of this study were to (i) determine whether current spring wheat cultivars and advanced experimental breeding genotypes vary in levels of susceptibility to Rhizoctonia root rot in inoculated field trials; and (ii) evaluate whether disease ratings obtained in growth chamber evaluations are predictive of, and consistent with, disease ratings in the field.
While the control of environmental variation through replicated field trials is important for analyzing resistance to root rot, the actual scoring method is equally significant.

The objectives of this study were to (i) use IBL populations to introgress Fusarium root rot resistance into the large-seeded Andean kidney and cranberry beans using a small-seeded black bean from the Middle American gene pool as the source of resistance; and (ii) identify significant QTL-marker associations which could be used to facilitate indirect selection for Fusarium root rot resistance in common bean.
