Glass1, William S. Gazaway2, and Edzard van Santen 3 Agricultural Program Associate and Professor, respectively, Dept. of Agronomy and Soils, Auburn University, AL 36849 2 Professor Emeritus and Extension Pathologist/Nematologist, Dept. of Entomology and Plant Pathology, Auburn University, 36849 1,3 Cotton cultivars and elite breeding lines submitted by 32 cooperators were evaluated for Fusarium wilt resistance under field conditions at the E. V. Smith Research Center, Plant Breeding Unit, Tallassee, Alabama. These entries were grown on an Independence loamy fine sand highly infested with the Fusarium wilt fungus (Fusarium oxysporum) Schlect. f. vasinfectum [Atk.] (Snyd. & Hans.) and southern root-knot nematodes (Meloidogyne incognita.). In 1994, a soil analysis for nematodes revealed that southern root-knot (Meloidogyne incognita) and lance (Hoplolaimus galeatus) are the predominant nematode species in the test plots. High populations of both species are found throughout the test area. Other nematode genera present are stubby root (Trichodorus sp.) and stunt (Tylenchorhynchus sp.). Root-knot nematodes, however, appear to be causing the major damage to cotton in the Fusarium Wilt Test as indicated by the high galling indices found on the roots of all cotton lines. Entries were planted in single 20-foot rows on 40-inch centers, separated by 5-foot alleys. Four replications of the test entries and checks were evaluated in a randomized complete block design with a split plot restriction on randomization. The set of eight test cultivars submitted by a cooperator was always evaluated as a group together with two control plots within each replicate. Both susceptible (Rowden) and resistant (M-315) cultivars were included as check subplots in the two center rows of each main plot (Fig. 1). Plots were planted May 17. Initial plant counts were made on June 9. Wilted plants were counted and removed on July 12, July 26, August 9, and August 23. The remaining live plants were counted and recorded on August 30. Total percent wilted plants were then determined and mean wilting for a given entry calculated. The average % wilted plants for the susceptible check Rowden was 82%, with a range from 40 to 100% on an individual plot basis (Fig. 1). Wilt development was quite uniform in all blocks with rep averages ranging from 73 to 87%. The resistant check M-315 had an average of 2% wilted plants, with a range of 0 to 13%. Critical evaluations of breeding lines should be made relative to the Rowden check listed at the bottom of each group. 4 ALABAMA AGRICULTURAL EXPERIMENT STATION Fig. 1.
