Entries were planted in single row plots, 22' long, on 30" centers, with three replications at Thief River Falls, MN. No artificial inoculations were made but the field was in an area known to have severe Phomopsis the previous year. Counts of diseased plants were made on Sept. 17 and Oct. 2, or approximately 4 weeks post bloom and at physiological maturity of most entries. The second disease rating (Oct. 2) was recorded for plots which had < 20% disease at the first rating. The simple, total percentage of Phomopsis infected plants includes plants with any Phomopsis symptoms. Disease data on late-maturing entries, however, should be viewed with caution as there was not sufficient growing season for adequate disease development on these accessions.
