VARIETY TRIALS OF UPLAND COTTON

Hugh A. Peacock!/

We have grown a cotton variety trial at AREC, Jay for the last 13 years to
determine those varieties best adapted to this area and to provide a basis for
variety recommendations by the Extension Service. Variety trial results for 1992
and averages over several years are included in this report. Also included are
results from variety trials grown in Santa Rosa and Escambia counties; AREC,
Marianna; NFREC, Quincy; and AREC, Jay; as well as variety trials grown in Tifton,
Plains, and Midville, Georgia; and Fairhope, Brewton, Headland, and Monroeville,
Alabama. From comparison of these reports, one should be able to determine the
cotton variety best adapted to a general area.

EXPLANATION OF DATA

Harvest of Seed Cotton:
Tests at AREC, Jay, Santa Rosa, Fairhope, Brewton, Headland, Monroeville,
Tifton, Plains, and Midville were harvested by a mechanical spindle picker. Tests
at AREC, Marianna; NFREC, Quincy; and Escambia County were harvested by hand.
Average yield of seed cotton was determined for each variety at each location.

Lint Percentage:
Seed cotton samples from each variety were ginned on a 10-saw gin. Lint
percentage was calculated by dividing weight of lint by weight of unginned seed
cotton and multiplying by 100.

Lint Yield:
Lint yield was determined by multiplying seed cotton yield by lint percentage
for that variety. Lint yield from Florida tests was determined by multiplying seed
cotton yield by 0.39, an average lint percentage figure.

Fiber Properties;

Length. For Alabama tests, this is the fiber length measured with the HVI
instrument and approximates classes' staple. For Georgia tests, this is the fiber
length measured with the Digital Fibrograph. The 2.5% S.L. is the length in inches
and approximates classer's staple.; 50% S.L. is length in inches of the test fiber
specimen spanned by 50% of the fiber scanned. S.L. is span length.

Strength. A measure of the fiber strength of a bundle of fiber measured with
two jaws holding the fiber bundle separated by 1/8 inch, expressed in grams force
per tex. Tex is a size measurement of the fiber bundle expressed as the mass, in
millimeters, of 1 meter of the fiber filaments. The data are given as the force,
in grams, needed to break this bundle; also noted in Georgia data as T1. The
higher the number the stronger the fiber.

Elongation (Ei). A measure of the percentage stretch before the fibers break.

1/Professor and Center Director, University of Florida, Institute of Food and
and Agricultural Sciences, AREC, Jay.









Micronaire. This measures the fineness of the cotton fibers taken from the
ginned lint. The smaller the micronaire reading, the finer and/or more immature
the fibers. The desirable range of micronaire is 3.5 to 4.9.

Uniformity or Uniformity Ratio (UR). Ratio' of 50% S.L. to 2.5% S.L.

Earliness:
Where more than one harvest was made, earliness is reported as the percentage
of the total yield harvested at the first picking.

Fusarium Wilt:
Reaction of varieties to Fusatium oxysporium f. vasinfectum was evaluated
under field conditions at the E. V. Smith Research Center at Shorter, Alabama.
These data are courtesy Dr. W. C. Johnson, Professor of Agronomy and Soils,
Auburn University, retired; Dr. A. J. Kappelman, Jr., USDA, ARS, Auburn Univer-
sity, retired; and Kathy M. Glass, Research Assistant in Agronomy and Soils,
Auburn University.

RESULTS

AREC, Jay:
The AREC, Jay cotton variety test is a continuing evaluation of available
cotton varieties from private companies and state agricultural experiment sta-
tions. Breeding lines that are likely to be released are also tested. We try to
test only those varieties and strains that will be adapted to the North Florida-
South Alabama area. Cultural practices are those generally recommended by
University of Florida to farmers. Every effort is made to test the varieties and
present the results in an unbiased manner. Appropriate analyses of the yield data
were made. The variability in the test was measured and expressed as a percentage
of the test mean, that is,..the coefficient of variation (CV). An indication of the
magnitude of difference between variety averages necessary to be considered a real
difference is given for each location and is designated as the Least Significance
Difference (LSD05 and LSD01).

Thirty-three cotton varieties were tested in a single trial replicated four
times in 1992 on a Red Bay sandy loam to determine yield. All varieties were
planted April 27 at the. rate of 20. bs/acre acid delinted seed. A preplant
application of 250 lbs/acre 8-24-24 was disked into the soil along with Treflan
and Vernam. The stand was thinned to 3-4 plants/foot of row. Ammonium nitrate was
applied as a top-dressing at 200 lbs/acre plus 7 lbs/acre nitrogen from urea two
times. The plots were harvested November 18. No supplemental water or potash was
applied.

Yields were good for most varieties. The overall mean for the test was 965
lbs lint/acre, about 300 lbs lint/acre less than in 1991. The data on yield at
AREC, Jay in 1992 along with 2-, 3-, 4-, 5-, and 6-year average yields are shown
in Table 1. The highest yielding variety of the varieties grown 3 years was
Deltapine DES119; the highest yielding variety of varieties grown 6 years was
Stoneville. KC-311. Highest yield in 1992 was: from a variety released from the
Mississippi breeding program, MD51 ne.

Statewide Tests:
Data on yield of several cotton varieties grown at 5 locations in North
Florida are presented in Table 2. A test scheduled for Okaloosa County was never
planted because of unfavorable planting conditions. The highest yielding variety
from the 5-location average was MD51 ne followed closely by Chembred 1135. The
highest yielding variety from the two Santa Rosa location average was MD51 ne
followed by Stoneville KC-311, Suregrow 1001, and Chembred 333 (Table 3).

New Strains Test:
Data on yield of several new strains grown in a test at AREC, Jay on Red Bay
sandy loam are presented in Table 4. Of the new cotton strains, PD-5246 was high-
est in yield followed by GA88-15-19, PD-5529, and Seed Source 9207. Yields were
fair with an overall mean of 892 lbs lint/acre.

Climatological Data:
A summary of the climatological data for the Agricultural Research and
Education Center, Jay for 1992 is shown in Table 5. The AREC, Jay climatological
gathering location is an official weather station.

Georgia Tests:
Data on yield and other characteristics of cotton varieties grown at Tifton
(Tables 6, 7, 8, 9), Plains (Tables 10, 11, 12), and Midville (Tables 13, 14) are
presented for your perusual. Of special interest might be Table 9 which presents
data on high quality (long and strong fibers with desirable micronaire) varieties
that might be grown in this area. Length, strength, and fineness values for each
variety in this test should be the values that could be expected from those same
varieties grown in North Florida. Yields would differ.

Yields in the variety trial at Tifton were excellent (Table 6) with the overall
mean of the test 1427 lbs/A lint. Highest yielding variety was Stoneville KC-311
followed by Deltapine 51. There was no significance difference in yield among the
first 13 entries.

The new strains tests at Tifton (Tables 7, 8) show yield and other charac-
teristic differences among the elite strains from breeders. Overall average yield
of Test I was 1441 lbs/A lint and of Test II was 1286 lbs/A lint.

The data presented in Table 9 are from high quality varieties grown at Tifton.
Acala 1517-88 should have the highest strength and longest fibers and may be used
as a check for length and strength of the other entries tested.

Alabama Tests:
Data on yield and other characteristics of cotton varieties grown at Fairhope
in 1992 are presented in Table 15. The highest yielding variety in 1992 was Stone-
ville X84-828. The highest yielding variety of varieties grown 3 years was Deltapine
51 followed closely by Deltapine 20..

Data on yield and other characteristics of cotton varieties grown at Brewton
in 1992 are presented in Table 16. The highest yielding variety in 1992 was Stone-
ville 132 followed closely by Deltapine 51. The highest yielding variety of
varieties grown 3 years was Deltapine 5690 followed closely by Stoneville KC-311
and Deltapine 51.

Data on yield and other characteristics of cotton varieties grown at Monroe-
ville in 1992 are presented in Table 17. The highest yielding variety in 1992 was
Stoneville 132 followed by Stoneville LA887. The highest yielding variety of var-
ieties grown 3 years was Stoneville KC-311 followed by Deltapine 5690 and Deltapine
5415.

Data on yield and other characteristics of cotton varieties grown at Headland
in 1992 are presented in Table 18. The highest yielding variety in 1992 was Delta-
pine 90 followed by Stoneville LA887. The highest yielding variety of varieties
grown 3 years was Deltapine 90 followed by Deltapine 5690 and Stoneville KC-311.

Fusarium Wilt:
Data from the fusarium wilt test at the E. V. Smith Research Center, Shorter,
Alabama showing performance of commonly grown varieties are shown in Table 19.
These entries were grown on an Independence loamy fine sand highly infested with
both the fusarium wilt fungus (Fusarium oxysporium Schlect. f. vasinfectum [Atk.]
Snydand Hans.) and rootknot nematodes (Meloidogyne spp.). Plots were 40-inch-wide
bedded rows, 30 feet long, separated by 6-foot alleys. Four replications of the
test entries and checks, arranged in a block design, were evaluated. Both suscep-
tible (Rowden) and resistant (Auburn 56) cultivars were included as checks. Rowden
was planted in row 5 and every tenth row thereafter and Auburn 56 was planted in
row 10 and every tenth row thereafter throughout the test. Plots were planted May
14, 1992. Initial plant counts were made on June 18. Wilted plants were counted
and removed July 15, August 3, August 17, and August 24. The remaining live plants
were also counted and recorded August 24. Percent wilted plants was then determined
and mean wilting for a given entry calculated.

The data in Table 20 is a summary of the data in Table 19. The wilt percen-
tage of any variety in Table 20 should be interpreted in relationship to the
readings for the nearest susceptible and resistant checks.

Production Costs:
The estimated costs of producing an acre of cotton in North Florida and
break-even prices are presented in Table 21.

Recommended Varieties:
Varieties recommended by the University of Florida, IFAS, Florida Extension
Service that should yield well under normal conditions are as follows:
Stoneville Coker 310 Deltapine 41
Stoneville Coker 315 Deltapine 50
Stoneville KC-311 Deltapine 51
Stoneville 506 Deltapine 902/
Stoneville 8251/ Deltapine 5415
Tifcot 56 Deltapine 5690
Chembred 1135 Deltapine DES119

I/Stoneville 825 is more susceptible to Fusarium wilt than any other variety on
the recommended list and should not be planted on land with a history of Fusarium
wilt.
2/To get the best performance from Deltapine 90, care must be taken to prevent
excessive growth. A common error is to over fertilize. On the heavier soils of
Florida, N fertilization should not exceed 50 lbs/A unless you have a history of
Deltapine 90 performance on the soil. If too much N is applied, excessive plant
growth and poor boll retention will result. In addition, lower bolls will be
more susceptible to boll-rotting organisms.
