.i ALABAMA COTTON VARIETY TESTS 1971 Wiley C. Johnson, Jr. January 1972 Department of Agronomy and Soils Departmental Series No. 2 A report of the performance of cotton varieties tested at nine locations in Alabama during 1971. Agricultural AUBURN E. V. Smith, Director Experiment Station UNIVERSITY Auburn, Alabama EXPERIMENTAL PROCEDURE Design and Location A randomized block design in four replications was used at each of the nine locations. All locations are on units of the Agricultural Experiment Station. Length of plots varied from 40 to 143 feet depend- ing upon available space. All plots were single-row except at Prattville where 2-row plots were used. Seasonal Conditions Early weather throughout the State was unusually cold and wet result- ing in late planting, considerable replanting and often poor stands. The damage of a poor start was largely alleviated by near ideal conditions that prevailed from mid-summer through harvest. It was necessary to replant most variety tests. The test at Tallassee was not harvested because of poor stands. Insect populations were not excessive and were adequately controlled. Variety performance at Headland was extremely variable and not consistent with previous years or with performance at other locations in 1971. Explanation of Data Yield of Seed Cotton: Tests at Prattville, Belle Mina, and Crossville were harvested with mechanical pickers. Tests at other locations were hand picked. Average weight of seed cotton per acre was determined for each variety. Lint Percentage: A sample of seed cotton of each variety from each location was taken at the first harvest and ginned on a 10-saw gin. Lint percentage was obtained by dividing weight of lint by weight of seed cotton. Yield of Lint: Lint yield was determined by multiplying yield of seed cotton by lint percentage. Fusarium Wilt Percentage: Wilt percentage was determined by removing and counting wilt infected plants three times at 3 to 4-week intervals. Observations were made at the Plant Breeding Unit, Tallassee, on fields known to be highly infested with Fusarium wilt and root-knot nematodes. On areas where wilt is known to be a problem, susceptible varieties should not be planted. Earliness: Earliness percentage is calculated by dividing the first harvest yield by the total yield. Fiber Properties: Measurements of fiber properties are not available at this time. A supplement to this report will be made when this information is available. Approved Varieties Many factors are taken into account in approving varieties. Amount of lint per acre is one of the most important but certainly not the only factor of importance. Resistance to prevalent diseases, adaptability to mechanical harvesting, storm resistance, and seedling vigor are among other factors considered. The potential for producing a quality fiber in demand by the market is becoming increasingly important. The following varieties have been tested at least 3 years and are approved for use in Alabama. Those starred are resistant to Fusarium wilt. The unstarred varieties are either highly susceptible or have only moderate tolerance to wilt and should not be used on fields where this disease is a problem. The varieties are listed alphabetically and indicate no order of preference. 3 *Auburn 56 *Auburn M Coker 201 Coker 310 Coker 417 Deltapine 16 Deltapine 45A *Dixie King II Hancock *McNair 1032B *MoDel Stoneville 7A Stoneville 213 Note: Stoneville 603 has been tested 3 years and has performed well. At this date it has not been officially released because most available seed were destroyed in a warehouse fire. Stoneville 603 will be approved when it is released by its originators. The following varieties have been tested less than 3 years and are therefore approved on a trial basis only. Delcot 277. A new release from Missouri which has been tested under the experimental number Mo 63-277D. It is a high quality variety with some tolerance to Fusarium wilt. Hjy-Bee lOQA. A selection from Hy-Bee 100. Apparently this variety is basically the same as the parent variety with selection made to improve its fiber characteristics. Hy-Bee 200A. A selection from Hy-Bee 200. Like the previous variety, the new selection is probably not radically different from the original material from which it was selected. Rex Smoothleaf 66. A new variety closely related to and quite similar to the older Rex Smoothleaf. New and Experimental Varieties Acala SJ-1 and Paymaster 111. These varieties are not grown in the Southeast. They are standard check varieties for the Regional Variety Test which is national in scope and in which Alabama participates. Acala SJ-1 is grown in California and Paymaster 111 is grown in Texas and Oklahoma. Coker 310-70903. This is not a variety but an advanced selection from the variety Coker 310. Coker 711. This is a Coker breeding line of glandless cotton. It is not a commercial variety and was in the variety tests for observation only. Glandless cotton is of interest because normal cotton has numerous glands, especially in the seed, that contain a toxin, gossypol. Deltapine 6225. A new selection from the cross of Deltapine 45 X Stoneville 7A. Selected for high yield, high lint per cent and lodging resistance. It appears to have some Fusarium wilt resistance. It will be called Deltapine 25 and should be available in 1973. Frego Bract: This designates a type of cotton in which the floral bracts are distorted so that they are narrow and arch away from the floral bud. This characteristic has been found to be unattractive to boll weevils. The strain of Frego Bract tested by Auburn was in the variety Deltapine Smoothleaf. Thus Frego Bract and regular Deltapine Smoothleaf were included at several test sites to see if Frego Bract affected yield or maturity. Frego Bract is reported to reduce yield and cause lateness. Lockett BXL and Lockett 4289A. These varieties are grown in the Plains area of the Southwest. They are being used in some narrow-row experiments. They are included in the variety tests at several locations to observe their performance with standard practices in comparison to local varieties. McNair 210. An early, semi-determinate type that was developed especially for the northern part of the cotton belt or other areas where earliness was desirable. Seed will be in extremely short supply for 1972. McNair 511. This variety is similar in appearnce to the familiar McNair 1032 and 1032B. The main difference is that McNair 511 has a slightly longer fiber. It appears to have a high level of Fusarium wilt resistance. Few seed are available for 1972. Acknowledgement The author wishes to express appreciation to Dr. A. J. Kappelman, Jr., for Fusarium wilt ratings, and to superintendents J. K. Boseck, S. E. Gissendanner, Robert Moore, C. A. Brogden, F. T. Glaze, Emmett Carden, and J. W. Langford for growing and harvesting the variety tests. Table 1. Performance of Cotton Varieties in Northern Alabama, 1971 Yield of lint per acre Variety Belle Mina Crossville Winfield Av Lb. Lb. Lb.
