INTRODUCTION
The Alabama Cotton Variety Test is a continuing evaluation of available cotton varieties from private companies and state agricultural experiment stations. Breeding lines that are likely to be released as varieties are also tested. Tests are conducted on units of the Alabama Agricultural Experiment Station by Experiment Station personnel. Cultural practices are those generally recommended by the Alabama Cooperative Extension System to producers. Data are reported on irrigated tests at Belle Mina and Headland. No other tests received scheduled supplemental irrigation. Every effort is made to test the varieties and present the results in an unbiased manner.

EXPERIMENTAL CONDITIONS
Tests were split into early season and full season varieties. The maturity category for each variety was chosen by the company or cooperator. Deltapine NuCotn 33B and Sure-Grow 747 were included in both early and full season tests for comparison. Plot size was two rows at Prattville, Headland, Belle Mina, Shorter, and Fairhope. Row length varied at different locations from 20 to 120 feet. A randomized complete block design with four replications was used in all tests. The trial at Fairhope is not reported due to unfavorable weather conditions at harvest. Cotton varieties were evaluated in a producer’s field on a sandy loam soil in south Alabama naturally infested with reniform nematode (Rotylenchulus reniform), continuously cropped in cotton by Dr. Kathy McLean of the Dept. of Entomology and Plant Pathology at Auburn University. All varieties were evaluated with and without the use of a chemical nematicide to give an indication of possible tolerance to reniform nematodes. Unfortunately, this test was not harvested due to inclement weather conditions.

EXPLANATION OF DATA
HARVEST OF SEED COTTON
A 50-boll sample was taken by hand for ginning, then test plots were harvested by a mechanical spindle picker at all locations. Average seed cotton yield 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 seed cotton weight.

YIELD OF LINT
Lint yield was determined by multiplying the lint percentage by seed cotton yield.

FIBER PROPERTIES
Fiber qualities of all varieties were measured by the USDA-AMS Classing Office in Birmingham, Alabama using High Volume Instrumentation (HVI). Data are reported on a single composite sample of each variety from each location including the regional tests at Shorter and Belle Mina. Micronaire: This measures the fineness of the cotton fibers. The smaller the micronaire reading, the finer and/or more immature the fibers.

Length: This is the fiber length measured with the HVI instrument. This measurement of length is similar to the classer’s staple. Strength: This is a measure of breaking strength of a standard fiber bundle with the holding jaws separated by 1/8 inch. “Tex” is a size measurement of the fiber bundle and the data given are the force in grams needed to break this bundle. Uniformity: This is the ratio between the mean length and the upper half mean length of the fibers and is expressed as a percentage. Cotton with a low length uniformity may be difficult to process. Earliness: Earliness is reported as the percentage of the total yield harvested at the first picking where more than one harvest was made. Fusarium Wilt: Reaction of varieties to Fusarium oxysporum f. vasinfectum (Fusarium wilt) was evaluated at the Plant Breeding Unit, Tallassee. Breeder lines and selected released varieties were grown in a field with a high natural incidence of the fusarium wilt disease. In 2002, incidence of Fusarium wilt was moderate. The incidence ratings can be found in the 2002 National Fusarium Wilt Cotton Report, Departmental Series No. 246.

STATISTICAL ANALYSIS
Appropriate analyses of the yield data were made. For each location, the variability in the test was measured and expressed as a percentage of the test mean, i.e., the coefficient of variation (C.V.). An indication of the magnitude of difference between variety averages necessary to be considered a real difference is given for each location. It is designated as the Least Significance Difference (L.S.D..10). Appropriate care should be taken when using multi-location or multi-year averages. The genotype x environment interaction is often a significant source of variation, indicating that the varietal rankings are not consistent from one location to another or from one year to the next. Using multi-environment means in these instances can be grossly misleading.
