| Abstract/Contents: | "Tall fescue [Lolium arundinacea (Schreb.) Darbyshire], a cool season grass native to Europe and some parts of Africa, was introduced into the United States in the1800s as a forage grass. Tall fescue has become one of the major cool season turf species in United States because of its winter hardiness, persistence, adaptability to wider range of soils, and tolerance to shade and drought. Tall fescue has a deep root system that enhances drought tolerance and allows the plant to stay green longer in dry conditions. Tall fescue also has among the best heat tolerance of the cool-season grasses. These qualities have increased the use of tall fescue in home lawns, sports fields, golf course roughs, recreational fields, sod farms, and roadsides. One of the major limitations of tall fescue is susceptibility to brown patch, caused by the fungus Rhizoctonia solani, in warm and humid regions. Brown patch is a soil borne disease of both cool season and warm season turfgrasses which causes blighted, circular to irregularly-shaped patches to form in the turf which quickly fade to light brown. Breeding for disease resistance is one of the main objectives of the Rutgers breeding program. Here at Rutgers mowed space plant nurseries of thousands of individual plants are inoculated with the brown patch fungus and individuals that exhibit no symptoms of infection are used in the breeding material for cultivar development. Many of the newer cultivars and selections in the turf trails have been developed using these methods. Five tall fescue trials were established at the Rutgers Plant Biology and pathology Research and Extension Farm at Adelphia, NJ between 2012 and 2015. All tests were established in September by hand sowing a 5.9 lb. per 1000ft2 rate in a 3ft × 5 ft turf plot. All tests were arranged in randomized complete block design with three replications, and each plot had a 6-inch unseeded border to limit contamination. All turf trials were inoculated with Rhizoctonia solani infected sterilized Kentucky bluegrass seeds at a rate of 1 gram per square meter. Trails were managed to promote disease development by frequent irrigation and fertilization. Once symptoms of brown patch developed the trials were rated on a 1- 9 scale with 1 being brown patch infection throughout the whole plot and 9 being no symptoms present. All data were summarized and subjected to an analysis of variance. Means were separated using Fishers protected least significant difference (LSD) means separation test. The means for all trials ranged from 1.5 to 8.7. The cultivars and selections that were most resistant were Amity, Avenger II, GTO, and 3B3 composite. Even though these cultivars performed very well there is still room for improvement to brown patch in tall fescue and this will remain a top priority of the Rutgers breeding program." |
