L 1981 ALABAMA COTTON VARIETY REPORT- A Report of the Performance of Cotton Varieties Tested at Nine Locations in Alabama During 1981 Wiley C. Johnson 2/ The Alabama Cotton Variety Test is a continuing evaluation of avail- able 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 usually conducted on units of the Agricultural Ex- periment Station by Experiment Station personnel. In 1981, the Winfield test was- planted on a private farm near the Upper Coastal Plain Substation. Cultural practices are those generally recommended by Auburn University to farmers. Every effort is made to test the varieties and present the data in an unbiased manner. Experimental Conditions A randomized block experimental design with four replications was used at each location. Plot row length at different locations varied from 34-5 . to 100 feet. Plots were two-row at Prattville, Headland, Belle Mina, and Crossville. Single row plots were used at the other locations. Rainfall was adequate early in the season but slightly deficient during July and August at most locations in 1981. September and October were dry throughout Alabama. The drouthowas most severe at Winfield and at the E. V. Smith Re- search Center near Shorter (Macon County). Season temperatures were near normal throughout Alabama. Insect control was generally adequate. 1/ January 1982 2/ Professor, Department of Agronomy and Soils -2- Explanation of Data Harvest of Seed Cotton: Tests at Prattville, Brewton, Monroeville, Tallassee, and Belle Mina were harvested by a mechanical spindle picker. Tests at Winfield, Headland, Shorter, and Crossville, were harvested by hand. Average yield of seed cotton was determined for each variety at each location. Lint Percentage: A sample of seed cotton from each variety at each locatio was taken at harvest and ginned on a 10-saw gin. Lint-percentage was cal- culated by dividing weight of lint by weight of seed cotton. Yield of Lint: Lint yield was determined by multiplying the lint percentag by yield of seed cotton. Fiber Properties: Fiber qualities were determined by the Department of Textile Engineering, Auburn University. (a) Span length: This is the fiber length measured on the digital fibrograph. The figures given are the distance spanned by 2.5% and/or 50% of the fibers, where the initial point of scanning is 100%. The 2.5% length, in inches, approximates classer's staple. The ratio of the 2.5% and 50% span lengths is a measure of fiber length uniformity. (b) 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 metric measurement similar to Pressley 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. -3- (c) Micronaire: This measures the fineness and maturity of the cotton fibers. The smaller the micronaire reading, the finer and/or 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 by Dr. A. J. Kappelman, Jr., at the Plant Breeding Unit, Tallassee. The varieties were grown in a field 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, and Stoneville 825 have 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. New and Experimental Varieties Deltapine-90 has been developed for the San Joaquin Valley area of California. However, preliminary testing indicates it is a high quality, smoothleaf variety with broad adaptation. Deltapine NSL is a nectariless, smoothleaf variety. Deltapine 62 is a new variety that appears to be quite similar to the familar and widely-grown Deltapine 61. Deltanine 7148 and Deltapine (DPL) 7537-6150 are experimental lines and have not been released. Coker 208 is an advanced line that will probably be released and available for 1983. It is quite similar to Coker 201, a reliable favorite in Alabama that has been discontinued. Coker 80903 is a high quality line that has -not been released. Acala SJ-5 and Lockett 77 are varieties adapted to the western areas of cotton production and are included in certain Alabama variety tests as national standard varieties. GAT 72-56 and PD 4548 are experimental lines. 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, coefficient of variation (C.V.). An indication of the magnitude of difference between variety averages necessary to be con- sidered a real difference i.s given for each location, Least Significant Difference (L.S.D.. 0 5 ).
