Verticillium Wilt

Caused by the soil fungus, Verticillium dahliae and V. albo-atrum, Verticillium wilt is geographically distributed across a broad range ofhot climates. A single dominant gene, Ve, was discovered in 1932 with resistance to race 1 (Schaible et al. 1951). The first resistant cultivars were released in 1952 (Cannon and Wad-doups 1952) and today's cultivars carry the same resistance. Tracing the mapping of the Ve gene through scientific literature is problematic as it has been linked to chromosomes 4, 7, 9, and 12. In 1999, Diwan et al. (1999) proposed that Ve was located on the short arm of chromosome 9 near RFLP marker GP39. A codom-inant SCAR marker has been developed that should be useful in breeding (Kawchuk et al. 1998).
