hybrids between Solanum lycopersicum L. and S. habrochaites S. Knapp & D.M. Spooner
A vascular disease of interspecific tomato hybrids caused by the fungi Verticillium dahliae and Verticillium albo-atrum. Resistance to race 1 of the pathogen is provided by the Ve1 gene, though breeding also focuses on identifying additional quantitative resistance loci in wild species.
In the reference 77 varieties crop hybrids between Solanum lycopersicum L. and S. habrochaites S. Knapp & D.M. Spooner, where this is mentioned in the description.
The disease is caused by the imperfect fungi Verticillium dahliae and, less frequently, Verticillium albo-atrum. For tomato, the division of the pathogen into race 1 and race 2 is fundamental, where resistance to the former is controlled by the Ve locus, which includes the Ve1 and Ve2 genes. When utilizing the wild species Solanum habrochaites in breeding, researchers often search for additional quantitative trait loci (QTLs) that provide broader protection than the classic Ve1 gene.
The first symptoms appear during the flowering or vegetative stage as unilateral yellowing of the lower leaves, followed by wilting that does not recover during nighttime hours. A diagnostic sign is the browning of vascular bundles in a cross-section of the stem; however, unlike Fusarium wilt, necrosis rarely extends more than 30 centimeters above the soil surface. In breeding materials, the presence of resistance is often denoted by the codes V or Vd.
