C. Johnson and Darrell Williams 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 usually conducted on units of the Agricultural Experiment Station by Experiment Station personnel. Cul- tural practices are those generally recommended byAuburn University to farmers. Every effort is made to test the varieties and present the results 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 40 to 120 feet. Plots were two-row at Prattville, Headland, Belle Mina,- and Crossville. Single-row plots were used at the other locations. Rainfall was abundant early in the season but less during August at most locations in 1982. September and October were dry throughout Alabama, giving near ideal harvest conditions. Climatic conditions were excellent for cotton production as indicated by a record high estimated state average yield of 736 pounds of lint per acre. The data from the tests at Winfield and Shorter were not suitable for inclusion in this report. -1- 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 Headland 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 location was taken at harvest and 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 on the digital fibrograph. The figures given are the distance spanned by 2.5 percent and/or 50 percent of the fibers, where the initial point of scanning is 100 percent. The 2.5 percent length, in inches, approximates classer's staple. The ratio of the 2.5 and 50 percent span lengths is a measure of fiber length uniformity. Stel ometer 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 Pressley strength except the figures are in grams per tex. -2- Tex is a size measurement of the fiber bundle. The larger the T 1 , the stronger the fibers. E I 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 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 62 is a new variety that appears to be susceptible to fusarium wilt, but otherwise is similar to the widely grown Deltapine 61. Deltapine 150 is a newly released variety previously tested as D.P. 7537-6150 and D.P. 6150. Coker 208 has been released and will be available in limited quantities in 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 from the Georgia Coastal Plain Experiment Station, Tifton and the Pee Dee Experiment Station, Florence, South Carolina, respectively. 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 considered a real difference is given for each location, Least Significant Difference (L.S.D..05 ) LOCATIONS OF EXPERIMENTS Tennessee Valley Substation, Belle Mina - W.
