Delta and Pine Land
Company announced the introduction of new high-yielding Acala and
Pima cotton varieties for 2001.
The announcement was
made at today’s New Developments in Industry session of the 2001
Beltwide Cotton Conferences in Anaheim.
DP 6207 Acala was
developed as a complete package for the San Joaquin Valley in
California. The variety has exceptional yields, exceeds the Acala
quality standard and is the earliest maturing Acala variety
available. It also doesn’t string out or end up on the ground,
is heat tolerant, resistant to Verticillium wilt and
demonstrates significantly lower seed coat fragments It was
approved for release by the San Joaquin Valley Cotton Board
(SJVCB) for the 1999 field season.
"DP 6207 Acala
demonstrated a five percent higher yield (59 lbs./acre) over 15
locations than the standard, Maxxa, in both wilt and non-wilt
soils, in 1997-1998 SJVCB Acala Variety Trials," says Dr.
James M. Olvey, president of O&A, Inc. of Maricopa, Ariz. and
breeder of DP 6207 Acala. "The higher yields were consistent
whether DP 6207 Acala was planted in 30" or 40" rows. It
out-yielded Maxxa by eight percent
(118 lbs./acre) in the
University of California Cooperative Extension Trials in 2000.
"When we take a
look at fiber characteristics, we find that DP 6207 Acala exceeds
the standard in length, strength and yarn tenacity," Olvey
says. "Although the individual fiber characteristics provide
a piece of the picture for fiber quality, it is really the
spinnability of the fiber when it reaches the mills that is most
important. When we look at the carded 50’s break factor, DP 6207
Acala exceeds Maxxa," Olvey says.
SJVCB research showed
that DP 6207 Acala has: excellent wilt resistance when compared to
other upcoming varieties; ten percent less seed coat fragments
than Maxxa in hot years such as 1997 and 1999; minimal ground
cotton due to its compact boll; and 60 more pounds of seed per
bale or 180 more pounds of seed per acre (at three bales per acre)
than Maxxa, which results in an increase in value of $14-$16 per
acre.
DP 340 Pima is a new
high-yielding early-to mid-season variety with excellent seedling
vigor, high-quality fiber and is adaptable across the entire Pima
Belt. It has been released for the 2001 season in Ariz., N. M. and
Texas and has been submitted for approval to the SJVCB for the
2001 season. Dr. James Olvey was also the breeder for DP 340 Pima.
Across the Pima Belt,
DP 340 Pima consistently out-yielded the standard, S-7, in Calif.,
Ariz., N. M. and Texas.
In the SJVCB (CA)
Variety Trials, DP 340 Pima consistently out-yielded S-7 and
PHY-76 in all three years tested (1998-2000), according to Olvey.
Those trials showed that the average yield increase for DP 340
Pima was 72 lbs./acre (six percent) over S-7 and 122 lbs./acre (10
percent) over PHY-76. In Texas, DP 340 Pima demonstrated an
11- percent increase
in yield over S-7.
In the 2000 Arizona
Pima variety trials, DP 340 Pima showed a four-percent increase in
yield over S-7 and a three-percent increase over DP 744 Pima,
while in New Mexico it showed a two-percent yield advantage over
S-7.
"DP 340 Pima has
excellent grades and consistently grades better (1’s and 2’s)
than
S-7 (2’s and 3’s),
according to SJVCB tests in 1998 and 1999," says Olvey.
"This is important since the difference between a 2 and 3
grade could mean a discount of up to six cents per pound of
lint."
In yarn strength for
combed 80’s variety trials conducted by SJVCB in 1999,
DP 340 Pima exceeded
both S-7 and PHY-76.
Both DP 6207 Acala and
DP 340 Pima have been licensed to Delta and Pine Land Company as
part of the company’s long-standing commitment to the Acala and
Pima markets.
