Anaheim, California
January 9, 2001
Delta and Pine Land Company
announced the company is introducing two new stripper Roundup
Ready® cotton varieties for the 2001 growing
season: Paymaster PM 2156 RR and Paymaster PM 2379 RR. The
announcement was made today at the New Developments in Industry
session of the 2001 Beltwide Cotton Conferences in Anaheim.
"The introduction of Roundup
Ready varieties to the stripper market in 1997 has surpassed
initial expectations and has allowed for increased research and
development of new varieties," says Tom Speed, High Plains
technical services director for Delta and Pine Land Company.
"PM 2156 RR and PM 2379 RR raise the bar to a new standard
for early-maturing and mid-full season stripper varieties."
PM 2156 RR is an early-season,
high-yielding, determinant variety with semi-smooth leaf
pubescence. Plant height is medium with seed size ranging from
4,200 to 4,600 seeds per pound. Storm resistance of open bolls
is rated fair.
PM 2156 RR has yielded an average
7.8 percent higher than its recurrent parent,
DP 2156, in 34 tests conducted in
1999 and 2000 (Table 1). Good seedling vigor coupled with high
early-season fruit retention and large bolls have been key
components for PM 2156 RR performance (Table 2). Seed supply for
the variety will be somewhat limited in 2001 due to the high
demand for early-season stripper Roundup Ready varieties.
PM 2379 RR is a medium to
full-season, indeterminant, stormproof stripper variety that has
shown wide adaptation across the Texas High Plains. The variety
has good early-season vigor compared with other commercially
available stripper varieties. Seed size ranges from 4400 to 4800
seeds per pound.
"PM 2379 RR’s two
distinctive features are excellent yield potential and good
fiber quality," says Speed. "It also has very good
storm resistance and very good tolerance to Verticillium
wilt."
PM 2379 RR has an average yield
within 1 percent of DP 2379 (Table 3). PM 2379 RR has
out-yielded PM 2326 RR by 3.5 percent and PM 2200 RR by 6.4
percent over 37 trials conducted since 1998 (Table 4). Seed
supplies for 2001 growing season will be excellent for a
first-year commercial introduction.

additional yield information for both varieties:
