1a.Objectives (from AD-416)
To develop and coordinate uniform evaluation trials of turfgrass varieties and promising selections in the United States and Canada.
1b.Approach (from AD-416)
Coordinated national tests to increase the cost effectiveness of cultivar evaluations by reducing the total amount of time and resources necessary to obtain the information needed on performance of cultivars.
The National Turfgrass Evaluation Program evaluated trials of Kentucky bluegrass, tall fescue, fineleaf fescue, perennial ryegrass, bentgrass, bermudagrass, zoysiagrass, seashore paspalum and st. augustinegrass in 2008. Two new trials of bentgrass, managed as a putting green and as a fairway, were established in 2008, along with a new fineleaf fescue trial. Data was collected, submitted and published on all trials in 2008. Data collected included turfgrass quality ratings for each month of the growing season, genetic color, leaf texture, density, ratings of tolerance to stresses such as drought and cold, along with evaluations of tolerance to various diseases. Progress was monitored through either on-site visits or phone/email communications with trial cooperators.
