New varieties bring increased
potential in yields, economic benefits
Delta and Pine Land
Company (D&PL) is introducing three new high-yielding,
second-generation transgenic stripper cotton varieties for the
Texas High Plains: PM 2167 RR, PM 2266 RR and PM 2344
BG/RR. PM 2167 RR and PM 2344 BG/RR will be commercially
available for the 2002 growing season, while PM 2266 RR will be
available only in limited quantities. The announcement was made
at the New Developments in Industry Session of the 2002 Beltwide
Cotton Conferences in Atlanta.
"New diverse germplasm is the lifeblood of breeding operations,"
said Tom Speed, regional agronomist for D&PL. "Both of the new
Roundup Ready® varieties, PM 2167 RR and PM 2266 RR, have novel
germplasm and were bred specifically for the Texas High Plains.
They are improved, second-generation varieties that have the
potential to put more money in the pockets of farmers." Delta
and Pine Land commercially introduced Roundup Ready stripper
varieties to the High Plains in 1997.
"Our new improved, second-generation stacked product, PM 2344
BG/RR, is widely adapted and has shown increased average yield
and fiber length when compared to PM 2326 RR during the past two
years of testing," said Speed. "We believe High Plains farmers
will especially like the economic benefits this variety offers."
Paymaster introduced the first Bollgard® and Roundup Ready
"stacked" stripper varieties to the Texas High Plains in 1999.
PM 2167 RR
The key features for this early-season, high-yielding, Roundup
Ready stripper variety are its novel, diverse genetic
background, tolerance to Bacterial Blight, less hair than PM
2145 RR and more stormproofness then PM 2156. Its fiber
qualities are similar to PM 2156 RR and PM 2145 RR, while its
maturity is similar to PM 2156 RR. Yield consistency or
stability has shown to be excellent. Yield data from 2000 and
2001 have shown this variety produced more lint per acre than PM
2156 RR, PM
2145 RR, PM 2326 RR and PM 2200 RR. The intended market of
adaptation is the northern High Plains, where a very-early
season variety is needed. It is also a potential early-maturing
variety for late-season re-plant situations. Seed supplies are
expected to be limited for the 2002 growing season.
PM 2266 RR
This new high-yielding, medium maturity, semi-smooth leaf
stripper variety features novel germplasm, increased fiber
length and a wide area of adaptation for the Texas High Plains.
Yield consistency or stability has shown to be excellent. D&PL
and university yield research averaged across 32 trials in 2000
and 2001 shows PM 2266 RR outyielded PM 2326 RR and PM 2200 RR
by 1.2 percent and 11.5
percent, respectively. It has averaged slightly longer fiber
than PM 2326 RR and similar fiber length as PM 2200 RR. It has
consistently provided a much better fiber package than PM 2145
RR or PM 2156 RR over the past two years. The intended market of
adaptation is the northern and southern High Plains of Texas.
Seed supplies are expected to be very limited for the 2002
growing season.
PM 2344 BG/RR
This new Bollgard and Roundup Ready "stacked" stripper variety
features high yields, medium maturity, very good storm
resistance, a wide area of adaptation that performs well in both
the northern and southern High Plains environment, and has
averaged a longer staple length than PM 2326 BG/RR. It has been
widely tested in public and company field trials over the last
two years on the Texas High Plains. This variety has shown
stable yield consistency, an overall 2.1 percent yield advantage
over PM 2326 BG/RR, and a 3.8 percent yield advantage over PM
2280 BG/RR. Yield comparisons in the northern High Plains were
even more impressive, with a 3.3 percent average advantage over
PM 2326 BG/RR and a 5.8 percent average advantage over PM 2280
BG/RR. Overall, PM 2344 BG/RR averaged a 0.6 staple unit longer
than PM 2326 BG/RR, with a 0.8 percent average advantage in the
northern High Plains. This variety has very good resistance to
Fusarium and good resistance to Verticillium, but is susceptible
to Bacterial Blight.
