C. Johnson' 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. For the first time, data are reported on an irrigated test at Belle Mina. 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 A randomized complete block experimental design with four replications was used at each location. Row length varied at different locations from 20 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. Rainfall was generally adequate to excessive at all locations during the spring. After early July, rainfall was less than normal at most locations. In northern Alabama, the drouth was especially severe. 'Professor of Agronomy and Soils. 1-- The harvest season was warm, fair, and favorable for maturing and harvesting the crop. 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 were determined by the Auburn University Textile Engineering fiber testing laboratory using High Volume Instrumentation (HVI). Data are reported on a single composite sample of each variety from all locations except the regional tests at Shorter and Belle Mina. Length. This is the fiber length measured with the HVI instrument. This measurement of length is about the same as the classer's staple. Strength. A measure of breaking strength of a standard fiber bundle with the holding jaws separated by 1/8 inch. Tex is a size -2- measurement of the fiber bundle and the data given are the force in grams needed to break this bundle. Elongation. A measure of the percentage stretch before the fibers break. Micronaire. This measures the fineness 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 1991 fusarium wilt was severe in the test area. 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. Verticillium wilt is being identified more frequently in northern Alabama than previously reported. 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 -3- variety averages necessary to be considered a real difference is given for each location. It is designated Least Significance Difference (L.S.D*.). LOCATIONS OF EXPERIMENTS Tennessee Valley Substation, Belle Mina - W.B. Webster, Superintendent Sand Mountain Substation, Crossville - J.T.

Leland, Mississippi New Mexico State University Las Cruces, New Mexico -25- ~____~ __~ AAC n RECOMMENDED COTTON VARIETIES FOR ALABAMA The list of recommended varieties given below was prepared by the author of this report and Keith Edmisten, Extension Agronomist, based on variety test performance for a 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 listed alphabetically are: Coker 130 Chembred 219** Coker 315* Chembred 407** Coker 320 Chembred 1135** Deltapine 20 Deltapine 5415** Deltapine 50 Deltapine 5690** Deltapine 51 Georgia King** Deltapine 90 HS 23** DES 119 Stoneville LA 887** HS 46* Terra 207** KC 311 PD 3 Stoneville 453* Stoneville 907 Suregrow 1001 Terra C 40 Tifcot 56* Tropical 225 *Not suited for soils where fusarium wilt has been a problem. **Tested for two years only and recommended conditionally. -26-
