Narrative
Very dense, moderately dark green Kentucky bluegrass with improved turf quality performance. In seed production, is a medium strawed variety and is classified as late in seedhead maturity, meaning its seedheads emerge later from the boot than some other varieties. Head color at flowering is a sensitive differentiating factor for bluegrass. Rated an average 6.7 in head color, with 1 equal to no purpling, and 9 equal to dark purpling. By comparison, Midnight rated 7.3, Baron 5.5, and South Dakota Certified 3.0. Culm length averages 53 cm at maturity with a tapering at the edges of the plant. Panicles are similar in appearance to those of NuGlade, but are more brownish-yellow in color if compard side by side. Culms are also a little taller than NuGlade and the leaves slightly lighter green in seed production.

Pedigree
Description:
Originated as a highly apomicticm single-plant selection from an open-pollinated cross in the Jacklin Seed breeding nurseries in 1992. Parentage traces to breeding line 90-0499, which originated as a naturally occurring hybrid of Midnight Kentucky bluegrass. Breeding line 90-0499 was selected from a breeding nursery north of Post Falls, ID, on 9 July 1990 and produced a moderately open turf with little or no ergot in seed production. In June 1991, a plant of 90-0499 was hybridized with pollen from 20 other Kentucky bluegrass, the resulting progeny were planted in a spaced-plant field nursery of 400 plants in July.
