‘Pizzazz’ perennial ryegrass (Lolium perenne L.) (Reg. no. CV-225, PI 628980) is a turf-type perennial ryegrass developed with the participation of Advanta Seed Pacific, Albany, OR, and released by Turf Merchants Inc., Tangent, OR, in 2001. Germplasm obtained from the New Jersey Agricultural Experiment Station was used in its development. The first certified seed was produced in 2001.

Pizzazz is an advanced-generation synthetic cultivar selected from the half-sib progenies of 31 plants, which trace maternally to plants selected from eight different sources of germplasm. Thirteen percent of the 31 plants trace a plant selected from the Rutgers Golf Course in Piscataway, NJ, in 1991. Nineteen percent trace to a plant selected for improved stem rust resistance in the 1984 perennial ryegrass trial. Six percent trace to a plant selected for dark green color and very low growth habit from 4 Delaware Drive in East Brunswick, NJ. Fifty-two percent trace to plants selected from old turfs in New Jersey, New York, and the midAtlantic region of the USA starting in 1962. Progenies of each of these plants were subjected to many cycles of phenotypic and genotypic recurrent selection in greenhouse disease screening tests, spaced-plant nurseries, and single-plant progeny turf trials located in central New Jersey during the three decades before the final development of Pizzazz perennial ryegrass. Approximately six percent of the germplasm trace to a population related to ‘Premier II’ perennial ryegrass (Bonos et al., 2000).

Two turf trials, one containing 205 single-plant progenies, and the other containing 650 single-plant progenies were established at the Rutgers Plant Biology and Pathology Research and Extension Farm at Adelphia, NJ, in 1995 and 1996, respectively. These turf trials included many standard cultivars and experimental synthetics. Approximately 48 plants were selected from each of the 14 best performing single-plant progeny turf plots based on vigor, density, dark-green color and freedom from leaf spot disease (caused by Drechslera siccans Drechs.). They were subsequently transferred to a spaced-plant nursery in the fall of 1996 and became the source for 14 of the 31 parent clones. The remaining 17 parents were selected from a mowed spaced-plant evaluation trial containing 17 160 plants that was established in 1996 and contained only half-sib progeny from the Rutgers Breeding Program. All 31 plants were selected for increased shoot density, low growth habit, dark green color, and freedom from disease. They were established in an isolated two-replicate randomized crossing block with 31 clones totaling 62 plants during the fall of 1997. During the spring of 1998, approximately 50% of the plants were not harvested due to stem rust (caused by Puccinia graminis Pers.:Pers.) development after seed set and/or poor floret fertility. Seed was harvested from the 31 superior plants (both replicates from 15 clones and one plant from a 16th clone). The seed from these 31 plants were sent to Advanta Seeds Pacific, Inc. to establish an isolated 775-plant nursery in the fall of 1998. Before the onset of anthesis, 165 plants were rogued to increase uniformity of maturity, seed yield potential, and resistance to stem rust. Eleven of the 31 progeny lines were eliminated before seed harvest. Breeder seed from the remaining 440 plants was harvested in the summer of 1999. Approximately 95% of the seed contained a Neotyphodium spp. endophyte. This seed was used to establish a Foundation seed increase field during the fall of 1999 and was entered in the 1999 National Turfgrass Evaluation Program (NTEP) perennial ryegrass test (Morris, 2000).

Pizzazz is a medium-late maturing, low-growing, turf-type perennial ryegrass, with an attractive dark-green color, fine leaf texture, and medium-high shoot density (Morris, 2000). It showed excellent overall turf performance in NTEP trials with excellent spring green up and good resistance to leaf spot, stem rust, crown rust (caused by Puccinia coronata Corda var. coronata), and dollar spot [caused by Sclerotinia homoeocarpa (F.T. Bennet)] in NTEP trials (Morris, 2000). Pizzazz shows promise for superior turf performance on lawns, athletic fields and golf course fairways throughout regions where perennial ryegrass is well adapted.

Seed production of Pizzazz is limited to one generation of Foundation and two generations of Certified seed. U.S. Plant Variety Protection for Pizzazz has been applied for (PVP Application no. 200200060). Breeder seed is maintained by Turf Merchants, Inc.
