Buchanan, Director Department Series No. 58 Auburn University Auburn University, Alabama January 1981 1980 REGIONAL COTTON FUSARIUM WILT TEST RESULTS 1980 REGIONAL COTTON FUSARIUM WILT REPORT' A. J. Kappelman, Jr., and D. P. Moore 2 Elite breeding lines and cotton cultivars submitted by 25 cooperators were evaluated for fusarium wilt resistance under field conditions at Tallassee, Alabama. These materials were evaluated on a Wickham sandy loam soil which was highly infested with both the fusarium wilt fungus [Fusarium oxysporum Schlect. f. vasinfectum (Atk.) Snyd. & Hans.] and root-knot nematodes (Meloidogyne spp.). Plots were 40-inch-wide bedded rows 30 feet in length and separated by 6-foot alleys. Cultivars and lines were arranged in a randomized complete block design with four replications. Both susceptible ('Rowden') and resistant ('Stoneville 603') cultivars were included as gradient checks. Rowden was planted in row 5 (15, 25, ... , 305) and Stoneville 603 in row 10 (20, 30, ... , 300) and then in every tenth row thereafter throughout the test. Plots were planted April 25 and 26, then thinned to three to four plants per foot of row on June 2. Initial live plant counts were taken June 4. Wilted plants were counted and removed three times during the growing season, and counts of remaining live plants were made August 29. Percent wilted plants per plot was determined as differences between initial and final live plant counts. Percent mean wilting for each entry was then calculated. Environmental conditions greatly affected plant growth as well as wilt incidence and intensity. During the first week after planting, air temperatures IThis is progress report for information and guidance of cooperators, the interpretation of which may be modified with additional experimentation. 2 Research Plant Pathologist, USDA-SEA-AR, Adjunct Assistant Professor, and Research Associate, Department of Agronomy and Soils. varied from 83 to 52 F and the minimum low temperature averaged 57 F. During IM-ay the mean high temperature was 82 F while the mean low temperature was 63 F but varied from 49 to 69 F. In addition, 7.49 inches of rainfall occurred during May. Thus, a considerable amount of seedling disease occurred and plants were extremely unthrifty. From June through September 14, temperatures varied from 82 to 104 F with a mean air temperature of 92 F. During this period only 5.67 inches of rainfall occurred. As a result, plants were extremely drought stressed and early senescence occurred. Wilt symptoms of plants which were already infested with the causal organism progressed rapidly; however, additional infection and symptoms of wilting were difficult to detect. On August 18, plots were irrigated with 3 inches of water. Following this, some additional wilting occurred but not on early maturing entries. Average wilting over the entire test for Rowden was 70% but wilt incidence of this check ranged from 17 to 100%. In contrast, the mean incidence of wilting in Stoneville 603 was only 30% but ranged from 0 to 68%. As a result of this overlap in wilting between the resistant and susceptible check, entries with intermediate resistance are difficult to classify. Entries submitted by W. C. Johnson are commonly grown cultivars or highly advanced commercial materials; therefore, these are listed by name. Entries submitted by other cooperators are listed by their coded numbers. Additional information regarding the genetic background of a specific coded entry should be obtained from the given cooperator.
