ABSTRACT
To ensure that Louisiana cotton growers remain competitive in the U.
S. and global textile markets, cotton varieties are tested and evaluated
on an annual basis at test locations that represent soil and climatic
conditions across the cotton-producing areas of the state. These test
locations are the Dean Lee Research Station, Alexandria; the Red River
Research Station, Bossier City; the Northeast Research Station, St.
Joseph; and the Macon Ridge Research Station, Winnsboro. Varieties submitted
for testing were divided into two groups (early or medium) based on
maturity classification determined by the companies submitting the variety.
In 2002, 28 varieties were evaluated in the early maturity group and
30 varieties were evaluated in the medium maturity group. Each test
was planted in a randomized complete block design with four replications.
Yield was determined after defoliation by harvesting the center two
rows of each plot with a two-row mechanical harvester. Transgenic varieties
were evaluated in tests with non-transgenic cotton varieties and received
the same recommended cultural practices as the non-transgenic varieties.
Data from these tests are used by scientists of the LSU AgCenter to
develop a list of recommended and promising cotton varieties for the
state.
