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 perennial ryegrass, tall fescue, fineleaf fescue, bentgrass, bermudagrass, zoysiagrass, seashore paspalum, and St. Augustine grass. A new trial of Kentucky bluegrass was established at twenty-four locations in 2011. Data collected in 2011 was submitted, statistically analyzed and published on all trials in spring 2012. Data collected included turfgrass quality ratings for each month of the growing season, color, leaf texture, density, ratings of tolerance to stresses such as drought and cold, along with evaluations of tolerance to various diseases.
