Department of Agronomy and Soils Departmental Series No.55 Agricultural Experiment Station Auburn University R. Dennis Rouse, Director Auburn, Alabama Alabama Cotton Variety Report 1979 March 1980 I. 1979 ALABAMA COTTON VARIETY REPORTI! A Report of the Performance of Cotton Varieties Tested at Nine Locations in Alabama During 1979 Wiley C. Johnson2/ 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 Conditions A randomized block design in four replications was used at each location. Plot row length at different locations varied from 40 to 120 feet. Plots were two-row at Prattville, Headland, Belle Mina, and Crossville. Single row plots were used at the other locations. 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. Insect con- trol was generally adequate. 1/ March 1980 2/ Professor, Department of Agronomy and Soils 2 Explanation of Data Harvest of Seed Cotton: Tests at Prattville, Brewton, Monroeville, Shorter, Tallassee, and Belle Mina were harvested by a mechanical spindle picker. Tests at Winfield, 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 per- centage 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: Because of the time required for the detailed deter- minations 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: 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 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 1 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 consistently 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 Coker 3114 is an experimental variety and has not been released for planting in 1980. It is the policy of the Auburn University Agricultural Experiment Station to evaluate a limited 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. Neither variety is adapted to Alabama conditions. Deltapine 70 and Deltapine 41 are recently 4 released varieties. Deltapine 41 was previously tested as Deltapine 7141 and will have some seed available for planting in 1980. Deltapine 70 is primarily intended for the irrigated areas of the western United States and will not be tested further in Alabama. Statistical Analysis Appropriate analyses of the yield data were made. For each location, the variability in 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).
