SR 6000 tufted hairgrass (Deschampsia cespitosa)
is not only a new cultivar but an exciting
new species for turf usage. No other turfgrass
breeding program in the world has developed
a tufted hairgrass with such exceptional turf
quality. Tufted hairgrass is a circumpolar,
native wetlands grass found from the arctic
to temperate area sand in the Americas from
Greenland to Alaska, south to New Jersey,
West Virginia, North Carolina, Illinois, North
Dakota, New Mexico and California. In turf,
this species can be mowed as low as 1/2 inch
or left unmown for its decorative seedheads.
BREEDING
SR 6000 is the first tufted hairgrass developed
specifically by a U.S. breeder for use as
a primary turf. The original germplasm was
collected and screened in the United Kingdom
from material found in the British Isles.
The material was then brought to the US
and screened for leaf spot resistance, uniform
color, growing and mowing height and seed
yield. The ability to produce adequate seed
levels to be utilized in turf situations
has been verified in seed production fields.
PERFORMANCE
SR 6000 forms a dark green turf that resembles
a fine-textured tall fescue at higher mowing
heights. SR 6000 produces an upright turf
with incredibly high shoot density. This
high performance variety has very tough
leaves that make it extremely wear tolerant
once established. SR 6000 also has an extensive,
fibrous root system that tolerates droughty
conditions as well as wet or flooded soils.
