CIRCULAR 55 tit, CCL . to 1930 CIRCUAR 55JANUARY Results of Cotton Variety Tests 1926.1929 By H. B. Tisdale and J. T. Williamson AGRICULTURAL EXPERIMENT STATION OF THE ALABAMA POLYTECHNIC INSTITUTE M. J. FUNCHESS, Director AUBURN Results of Cotton Variety Tests 1926-1929 Alabama Experiment Station By H. B. TISDALE, Plant Breeder and J. T. WILLIAMSON, Associate Agronomist Eleven conclusive variety tests of cotton were conducted in different localities of North, Central, and South Alabama in 1929. The following tables give the results of these tests and the average results of all tests conducted over a period of four (4) years, 1926-1929. Tables 1 and 2 show the average results of 14 tests in North Alabama and 9 tests in Central Alabama conducted over a period of four (4) years, 1926-1929. Table 3 shows the length of staple of each variety in each locality. The five leading varieties with the average yield of lint cotton per acre and the average length of staple (in 1/32 inches) for the four (4) year period are as follows: North Alabama D. P.

Nothing but a wilt resistant variety of cotton should be planted on land subject to the wilt disease. The leading wilt resistant varieties of cotton, as shown in Table 4, compare very favorably in yield with the leading non-wilt resistant varieties, when grown together on noninfeste4d, soil. The loss from a non-wilt resistant variety of cotton grown on infested land will run from 10 to 100 per cent according to the degree of infestation of the wilt disease. * Not Wilt resistant.

The Super 7 variety has a staple length of 1 1/32 to 1 1/8 inches, but has a comparatively low yield and is rather hard to pick. The Cleveland (Ped. Seed Company) variety has been run in the variety tests for two years and the results show a very satisfactory yield with a staple length of 15/16 to 1 inch. The Alabama Experiment Station has no cotton seed for sale. The seed for the variety tests of cotton in 1929 were obtained from the following sources: D. P.
