NATIONAL TURFGRASS EVALUATION PROGRAM
Floral and Nursery Plants Research Unit
2010 Annual Report
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 objective of this research is to develop and coordinate uniform evaluation trials of turfgrass varieties and promising selections in the U.S. and Canada. 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 2009. A new trial comparing drought tolerance of cool-season grasses was established at five locations in 2009. Data was collected, submitted and published on all trials in 2009. Data collected included turfgrass quality ratings for each month of the growing season, genetic color, leaf texture, density, and 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.
