Interpretive Summary: Characterization of germplasm collections is critical to assess collection diversity and enhance utilization. This paper reports work in which the USDA Kentucky bluegrass collection was characterized for both molecular variation at the DNA level as well as agronomic variation. The results showed that both the molecular and agronomic characterizations were useful in determining overall diversity in the Kentucky bluegrass collection. The molecular technique was, however, better at determining misidentified accessions. Both approaches showed that not two accessions in the collection were duplicates but highly diverse material was generally under represented. The correlation between the molecular and agronomic-based techniques was significant but both molecular and agronomic characterizations were needed to assess overall diversity.
