Abstract
Fusarium graminearum was identified as a root pathogen of a diverse array of dry edible bean genotypes under both field and greenhouse conditions in North Dakota. In comparisons under controlled conditions, root rot caused by F. graminearum was equal or greater than that caused by F. solani f. sp. phaseoli. Out of eleven dry bean genotypes evaluated in controlled conditions, Eclipse, VAX 3, and T-39 had the lowest root rot severity values for both F. graminearum and F. solani f. sp. phaseoli. A significant and positive correlation between genotype response to F. graminearum and F. solani f. sp. phaseoli indicates that genetic resistance to both pathogens may be related.
