| Abstract/Contents: | "This long-term study consists of 10 Kentucky bluegrass (Poa pratensis L.) entries; eight are USDA/ARS Plant Introduction (PI) accessions and two are commercial cultivars ('Kenblue' and 'Midnight'). The selected PI accessions had expressed high seed yield without burning of postharvest residue and good turfgrass quality. Several agronomic yield parameters were then evaluated over a 2-yr period and individual plants were selected within each accession, or check, with the highest seed weight, highest seeds panicle-1, highest panicles area-1, and highest seed yield. Remnant seed of the original USDA/ARS population were also included. Turfgrass plots were established in 2006 and seed production plots (irrigated and non-irrigated) in 2007 at Pullman, WA. The turfgrass trial was evaluated monthly (2007 to 2009) according to NTEP (National Turfgrass Evaluation Program) protocol to determine turfgrass quality. In 2008 and 2009, seed production plots were harvested and seed yield was determined. Only 2009 results will be presented. The prior selection for seed yield components had a variable response and seed yield appeared to be dependent primarily on accession. Accession PI 368241 showed the best promise of being able to provide good turfgrass quality and good seed yield under non-burn management in both non-irrigated and irrigated production. Selection within Kenblue for seed head-1 had good turfgrass quality and seed yield under non-irrigated production. These studies will be followed for several additional harvests to determine if a non-burn Kentucky bluegrass can be developed for sustainable grass seed production in the Pacific Northwest, USA." |
