| Abstract/Contents: | "To estimate diversity within the USDA/ARS plant introduction collection of Kentucky bluegrass (Poa pratensis L.), 228 accessions and 17 commercial cultivars were evaluated for turfgrass, forage, and seed production parameters in field studies conducted from 1994 to 1996 at Pullman, WA. Experimental units consisted of 1.0 m strips with 0.31 m spacing between units in randomised complete-blocks with three replications. Significant variability was observed for all phenotypic and agronomic traits. The collection has been characterised by a representative core subset (one random accession chosen from each of 22 clusters) utilising cluster analysis (Ward method). The core represents approximately 10% of the accessions studied. Clusters were identified that exhibited high seed yield and good turfgrass and forage characteristics. Utilisation of this core collection will facilitate genetic resource management, the identification of genotypes for turfgrass breeding and other agronomic uses, and the identification of geographic regions offering promise for future germplasm collection. The core subset will allow a wide range of variability in the USDA/ARS Poa pratensis germplasm collection to be evaluated for many traits and in many environments. All data will be available on the Germplasm Resources Information Network (GRIN) database." |
