The
National Turfgrass Evaluation Program (NTEP: www.ntep.org) changed some of the
ground rules for testing grasses. The new program was first outlined in the
March 2010 TurfGrass Trends. The major change was a cutback from a five-year
test program to four years in a number of tests. The focus of some tests
changed, as well.
When we
checked back this month with Kevin Morris, executive director of NTEP, to see
how the changes were going, he was “encouraged” by early results but said it
still is a bit too early to tell definitely.
“We
just published our first data (under the new regime), a ryegrass test put out
in 2010,” he says.
As part
of the new program, half of the seed plots established around the country are
standard variety tests. The other half are what are termed “ancillary” tests –
they are specific to one aspect of the turf… say traffic tolerance or drought
resistance.
“We
will stay with that program for a while,” Morris says.
As the
number of commercial varieties available dropped, NTEP saw a need to move away
from the beauty-contest aspects of variety testing in favor of focused,
trait-specific research.
Last
year, NTEP started a major bluegrass testing program. This year, tall fescue is
the focus. Right now, Morris’s office in Beltsville, Md., is piled with tall
fescue seed samples.
The
industry trend in fescues had been to fewer varieties. But that is changing and
that change means there will be more activity in the ancillary test program on
traits like drought resistance and pesticide tolerance.
“The
seed industry definitely likes the new program and I’ve gotten positive comment
from users,” Morris concludes.
