A November, 1985 * Agronomy and Soils Departmental Series No. 104 Alabama Agricultural Experiment Station David H. Teem, Acting Director Auburn University Auburn University, Alabama A; 1985 REGIONAL COTTON FUSARIUM WILT REPOR 1985 REGIONAL FU.SARIUM REPORT" W. C. Johnson and Darrell Williams 2 Cotton cultivars and elite breeding lines submitted by 19 cooperators were evaluated for fusarium wilt resistance under field conditions at the Plant Breeding Unit, Tallassee, Alabama. These entries were grown on a Cahaba loamy fine sand 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, separated by 6-foot alleys. Four replications of the test entries and checks, arranged in a block design, were evaluated. Both susceptible (Rowden) and resistant (McNair 235) cultivars were included as checks. Rowden was planted in row 5 and every tenth row thereafter (15, 25,..., 205) and McNair 235 in row 10 and every tenth row thereafter (20, 30, ... , 200) throughout the test. Plots were planted May 1 and thinned to three or four plants per foot on June 18. Initial live plant counts were also made on that date. Wilted plants were counted, removed, and recorded on July 16, August 15, and September 18. The remaining live plants were also counted and recorded on September 18. 1 This report is a joint contribution between USDA-ARS, Crop Science Research Laboratory, Mississippi State, Mississippi, and the Alabama Agricultural Experiment Station, Auburn University, Alabama. 2 Professor of Agronomy and Soils and former Research Associate of Agronomy and Soils (currently Sumter County, Florida Extension Supervisor), respectively. Percent wilted plants per plot were then determined and mean wilting for a given entry aalculated. The incidence of wilt was high within the experimental area and was not excessively variable, appearing to be more or less randomly distributed. Average wilting of the susceptible Rowden was 65.8, 68.6, 81.4, and 60.8 percent for each of the four replications. The mean incidence of wilting in the resistant check, McNair 235, was 2.9, 5.8, 10.9, and 3.7 percent in the corresponding replications. Critical evaluation of a given entry should be made relative to the checks closest to the entry within each replication. Evaluation of breeding progress or evaluation of entries over years should be made only between the relative value of this entry and that of the closest susceptible check rows for each year. Entries submitted by W.C. Johnson are commonly grown cultivars or advanced commercial materials. Thus, these entries 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 named cooperator. ACKNOWLEDGMENT The authors express appreciation to A.J. Kappelman, Jr., retired, for advice and technical assistance in conducting the test and preparing this report. 1985 Regional Cotton Fusarium Wilt Test, Plant Breeding Unit, Tallassee, Alabama Test entry Percent wilt by replication Mean designation 1 2 3 4 Robert R.
