Interpretive Summary:

Technical Abstract: The objective of this test was to examine field emergence among different seedlots of the same commercial variety. Three varieties were available in which seedlots had been obtained in the same year from more than one grower (via the West Coast Beet Seed, Co., Salem, OR). Additional seedlots from different years were available in some instances, as well. All seedlots were commercially prepared by the Michigan Sugar, Co. and Monitor Sugar, Co. seed processing facilities. Field data was gathered for comparisons with germination data in liquid media (data not shown). For emergence, no significant statistical differences were evident between seedlots of the same variety grown in the same year, however variability between replications was high in all cases despite eight replications of the trial. Significant differences between varieties were evident. Agronomic performance did not appear to be correlated with emergence, although the best yields were seen with the best emergers.
