REGISTRATIONS OF CULTIVARS

Registration of ‘Quest’ Tall Fescue

Simplot/Jacklin Seed, West 5300 Riverbend Ave., Post Falls, ID 83854-9499

^* Corresponding author (mark.sellmann{at}simplot.com)

‘Quest’ tall fescue (Festuca arundinacea Schreb.) (Reg. no. CV-93, PI 633969) was developed by the J.R. Simplot Co., Jacklin Seed, Post Falls, ID, and released April 2001. First Certified seed was produced in 2001. Quest was tested under the experimental designation JT-1 and 98-8001.

Quest is a cultivar developed from the maternal progenies of 15 lines. The maternal germplasm sources contributing to Quest trace over several breeding generations back to 33% Simplot plant introductions, 33% ‘Pixie’ (Sellmann et al., 1997), 7% ‘Alamo E’ (Sellmann and Brede, 2000a), 7% ‘Brandy’ (Sellmann and Brede, 2000c), 7% ‘Arid 3’ (Sellmann and Brede, 2000b), 7% ‘Coronado’ (Rose-Fricker et al., 1999), 3% ‘Vegas’ (Alderson and Sharp, 1995), and 3% ‘Monarch’ (Rose-Fricker and Meyer, 1993). In April 1997, five lines were selected from a 1994 turf trial at Poolesville, MD, and 10 lines from a 1995 trial at Poolesville. Selection was based on superior turf color, net blotch (caused by Drechslera dictyoides Drechs.) resistance, brown patch (caused by Rhizoctonia solani Kühn) resistance, and overall turf quality. Plants were transferred from the field plots into greenhouse flats, and in June 1997, 4000 plants from the 15 half-sib progenies of selected plants were established in a breeder block near Rathdrum, ID. The field was rogued, keeping plants with finer leaf texture, dark-green color, high shoot density, and uniform height. Approximately 800 plants (20%) were removed before anthesis. Seed was harvested in July 1998 and designated 98-8001. In June 1999, a 2000-spaced-plant block of 98-8001 was planted at the same location. In 2000, approximately 30% of these plants were removed due to light green color, inconsistent plant height, poor seed yield, or disease susceptibility. First Breeder seed was harvested in July 2000 and designated JT-1. Seed from this harvest was entered into the 2001 National Turfgrass Evaluation Program (NTEP) tall fescue trial.

Results from the 2001 NTEP tall fescue trial were reported in 2003 and demonstrated that Quest had improved quality under high input conditions (Morris, 2003). In the same trial, Quest ranked 15th out of 160 entries for leaf texture and was comparable with ‘Avenger’, ‘Davinci’, ‘Justice’, ‘Blackwatch’, ‘Titanium’, ‘Raptor’, ‘Forte’, and ‘Kalahari’. Quest was finer textured than ‘Silverado II’, ‘Silverstar’, ‘Mustang 3’, Watchdog, and Wyatt. Brown patch disease ratings for Quest were comparable with the most resistant entries in the trial.

Quest is most similar to Pixie and Brandy; however, Quest has a narrower flagleaf than Brandy, and Quest has a shorter flagleaf sheath length and shorter panicle than Pixie.

Quest is a uniform and stable cultivar. Seed samples of Breeder, Foundation, and Certified seed have produced turfgrass with comparable quality and acceptable uniformity. As with any sexually propagated crop, variants will continue to occur in each generation, but these variants are infrequent and are routinely rogued from seedstock fields. Quest is recommended for sports fields, home lawns, parks, and golf course out-of-play areas where tall fescue is suitable for turf. It can be grown in full sun or moderate shade.

Breeder seed is maintained by Simplot/Jacklin Seed. Seed propagation is limited to three generations of increase, one each of Foundation, Registered, and Certified. U.S. Plant Variety Protection for Quest will not be applied for.
