C. Johnson 1 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 Auburn University to farmers. Every effort is made to test the varieties and present the results in an unbiased manner. EXPERIMENTAL CONDITIONS A randomized complete block experimental design with four replications was used at each location. Row length varied at different locations from 40 to 120 feet. Plot width was two rows at Prattville, Headland, Belle Mina, Shorter, Tallassee, Fairhope, and Crossville, and one row at Brewton and Monroeville. Climatic conditions at all locations were generally favorable during early season. After early June, rainfall was greater than normal at all locations. iProfessor of Agronomy & Soils. EXPLANATION OF DATA Harvest of Seed Cotton Tests at Prattville, Brewton, Monroeville, Tallassee, Belle Mina, and Shorter were harvested by a mechanical spindle picker. Tests at Headland and Crossville 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 seed cotton. Yield of Lint Lint yield was determined by multiplying the lint percentage by yield of seed cotton. Fiber Properties Fiber qualities of all varieties from selected locations were determined by Starlab, a commercial fiber testing laboratory in Knoxville, Tennessee. Span Length. This is the fiber length measured with the digital fibrograph. The 2.5 percent length is the average length of the longest 2.5 percent of the fibers, and the 50 percent length is the average length of the longest 50 percent of the fibers. The 2.5 percent length is about the same as the classer's staple. Stelometer. T 1 is a measure of breaking strength of a standard fiber bundle with the holding jaws separated by 1/8 inch. This, is a measurement similar to Presley strength except the figures are in grams per tex. Tex is a size measurement of the fiber bundle. The larger the T 1 , the stronger the fibers. E 1 measures the percentage stretch before the fibers break. 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 to 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 oxysporum f. vasinfectum (fusarium wilt) was evaluated at the Plant Breeding Unit, Tallassee. The varieties were grown in a field with a high natural incidence of the fusarium wilt disease. During 1989 fusarium wilt was more severe than usual. 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 825 has consistently shown a high incidence of wilt. All other reported varieties that have been tested for at least 3 years have acceptable tolerance to fusarium wilt. Verticillium wilt is being more frequently identified in northern Alabama than previously. Varietal comparisons reported in table 11 do not apply in any way to this disease. 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 Least Significance Difference (L.S.D. .05). LOCATIONS OF EXPERIMENTS Tennessee Valley Substation, Belle Mina -W. B.

Johnson, Professor of Agronomy, based on variety test performance for at least 3 years. Varieties differ in performance at individual locations, so selection should be based largely on variety performance at a site that most nearly represents the grower's local situation. As a general rule, a yield difference in the order of 10 percent is needed for varieties to be considered truly different. The recommended varieties are listed in order of 3-year average lint yield.
