| Abstract/Contents: | "Communities and local governments around the country are currently focused on reducing environmental impacts and costs of maintaining recreational and homeowner landscapes. Breeding programs are actively trying to develop turfgrass cultivars with improved performance under low maintenance conditions (which includes reduced pesticides, mowing, fertility and irrigation). Hard fescue (Festuca brevipila Tracy) has been identified as a potential candidate species for low maintenance turf areas, due to its excellent drought tolerance, and lower mowing and fertility requirement compared to traditional cool-season grass species such as perennial ryegrass (Lolium perenne L.) and Kentucky bluegrass (Poa pratensis L.). However, one of the major weaknesses of this species is its susceptibility to Magnaporthiopsis poae J. Luo & N. Zhang, the casual organism of summer patch disease. Summer patch can cause severe damage to a turfgrass stand to the point that complete renovation is required. Summer Patch can be controlled with fungicides; however, pesticide use in low maintenance situations is undesirable. Sixty-six entries of hard fescue were established in a mowed turf trial in a randomized complete block design at the Rutgers Horticultural Research Farm #2 in North Brunswick, NJ in the fall of 2012. Thirty-five hard fescue selections were established in a mowed spaced-plant trial in a randomized complete block design at the Plant Biology and Pathology Research and Extension Farm in Freehold, NJ in the summer of 2012. The mowed spaced-plant trial was inoculated with oats infected with Magnaporthioposis poae under each plant, while the turf trial at North Brunswick was not inoculated. Turf plots and mowed-space plants were visually evaluated in the summer months of 2013 and 2014 for summer patch disease severity. Resistance was measured on a visual scale from 1-9 (9= No symptoms). Significant and consistent differences in summer patch resistance were observed over the two years within each of the trials. Selections that performed well included A10-198, A10-207, and A10-219 with ratings of 6.28, 6.30, and 6.59. Traditional cultivars such as Beacon, and Aurora Gold had the least summer patch resistance with ratings of 3.59 and 3.95. Further research is being conducted to determine the narrow sense heritability of summer patch resistance within the hard fescue species. This information will provide insight into the level of resistance that can be obtained through traditional breeding strategies." |
