1978 ALABAMA COTTON VARIETY REPORT

A Report of the Performance 
of Cotton Varieties
Tested at Nine Locations in Alabama During 
1978

The Alabama Cotton Variety Test 
is a continuing evaluation of available
cotton varieties from private companies 
and state experiment stations.
Breeding lines that are likely to 
be released as varieties are also tested.
Tests are conducted on units of the Agricultural 
Experiment Station by
Experiment Station personnel. Cultural 
practices are as generally
recommended by Auburn University to farmers. 
Every effort is made to test
the varieties and present 
the data in an unbiased manner.
Experimental Design and Plot Size
A randomized block design in four replications was used 
at each loca-
tion. Length of plots at different locations 
varied from 34 to 110 feet.
Plots were two-row at Prattville and Belle Mina and 
single row at the other
locations.
Seasonal Conditions
All tests were planted within the optimum 
planting period. Most
varieties had acceptable stands but several 
rows were not harvested for
record or yields were adjusted to account for 
skips. The greatest adjustment
because of poor stand was at Prattville. 
The coefficient of variation for
this test was reasonably low which 
would support the validity of the yield
adjustments.
Insect control was generally adequate. 
However, at Headland the top

and Soils
bolls were almost completely destroyed by bollworms. Rainfall on the
E. V. Smith Research Center near Shorter was sparse all season. Most
other locations had normal rainfall through July but less than normal
rainfall thereafter. Moisture at Brewton and Crossville was adequate
throughout the season.
Explanation of Data
Harvest of Seed Cotton: Tests at Prattville, Brewton, Monroeville, Shorter,
and Tallassee were harvested by a mechanical spindle picker. Tests at
Winfield, Belle Mina, Headland, and Crossville were harvested by hand.
Average weight of seed cotton per acre was determined for each variety at
each location.
Lint Percentage: A sample of seed cotton from each variety 
at each location
was taken at harvest and ginned on a 10-saw gin. Lint percentage 
was calcu-
lated by dividing weight of lint by weight of seed cotton.
Yield of Lint; Lint yield was determined by multiplying the lint percentage
by yield of seed cotton.
Fiber Properties: Because of the time required for the detailed determina-
tions of the fiber properties, data presented in the current report 
are
from samples of the previous year. Fiber qualities were determined 
by the
USDA Cotton Quality Spinning Laboratory, Knoxville, Tennessee.
(a) Span length: This is the fiber length measured on the digital
fibrograph. The figure given is the distance spanned by 2.5%
of the fibers, where the initial point of scanning is 100%.
This length, in inches, approximates classer's staple.
(b) Stelometer: T1 is a measure of breaking strength of a standard
fiber bundle with the holding jaws separated by 1/8 inch. This
is a metric measurement similar to Pressley strength except the
figures are in centinewtons per tex. A centinewton is a measure
of force and a tex is a size measurement of the fibers. The
larger the T
1
, the stronger the fibers. E measures the
percentage stretch before the fibers break.
(c) Micronaire: This measures the fineness and maturity of the cotton
fibers. The smaller the micronaire reading, the finer and/or
more immature the fibers. The desirable range of micronaire is
3.5 - 4.9.
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 Fusarium wilt was evaluated at the
Plant Breeding Unit,. Tallassee, by growing the varieties in fields with a
high natural incidence of the fusarium wilt-root-knot nematode complex.
Severity of the disease varies from year to year and also within the
experimental area in the same year. Therefore, several years' data are
necessary to realistically characterize a variety's wilt reaction.
Stoneville 213, Hancock, Stoneville 
731N, Vail 7, and Brycot 4 have 
con-
sistently shown a high incidence of 
wilt. All other varieties that have 
been
tested for at least 3 years have acceptable tolerance to fusarium wilt.
New and Experimental Varieties
Several experimental varieties were tested in 1978. These are:
Coker 4601, Coker 315, Coker 6118, Coker 3114, Coker 420, and Deltapine 7141.
None of these have been released for planting in 1979. It is the policy of
the Auburn University Agricultural Experiment Station to evaluate a limited
4
number of such experimental varieties as a service to plant breeders and
also to enable the testing of potential varieties prior to their release.
Paymaster 303 and Acala SJ-5 are varieties adapted to the western areas
of cotton production and are included in certain Alabama variety tests as
national standard varieties. These tests are part of a national cooperative
variety: testing program. Neither variety is adapted to Alabama conditions.
Rex 731 has been tested previously as "New Rex". The variety is the same;
only the name has been changed. DES 56 was developed by the Mississippi
Agricultural Experiment Station and is being tested in Alabama for the first
time in 1978. Stoneville 825 is a nectariless variety similar to Stoneville
731N. McNair 235 has been previously tested at certain locations as 
McNair
3035. This is the first year it has been entered in the regular variety
tests.
Statistical Analysis
Appropriate analyses of the yield data were made. For each location, the
variability of the test was calculated and expressed as a percentage of the
test mean, coefficient of variation (C,V.). An indication of 
the difference
between variety averages necessary to be a real difference is given, Least
Significant Difference (L.S,D. 05)
