“…Some resistance to Verticillium exists in cultivated Solanum germplasm. For example, resistance has been reported in cvs Rideau (Johnston & Rowberry, 1980), Ute (Holm et al, 1987), Reddale and Russette (Wheeler et al, 1994) and breeding clone B0169-56 (Goth et al, 1994). Susnoschi et al (1976) have also reported moderate to high levels of resistance in some cultivars.…”

SummaryVerticillianl dahliae causes potato (Solarium tuberosam) early dying disease. Interspecific hybrids containing S. tuberosunl, S. berthaaltii, S. bukasovii, S. chacoense, S. gourlayi, S. sparsipilum and S. tarijense were identifed with resistance to V. dahliae. Clones were grown in replicated trials for three years in a plot containing approximately 50 colony forming units (cfu) V. dahliae per g soil. Clones were evaluated for vine maturity, early dying symptoms and stem colonization. Five resistant 2x clones were identified with early maturity and low levels of stem colonization. A single maturity score and one disease score, each obtained in mid-August, were sufficient to distinguish among clones. An effective threshold level for considering a stem to be infected was determined to be 25 cfu/100 ial sap. Early dying symptoms did not correlate strongly with stem colonization. Numerous stems must be sampled when making resistance assessments. The average cfu/100 IJI sap correlated strongly with the number of infected stems.

“…In India, two cultivars were rated as moderately resistant (33-47% incidence), while another 18 cultivars were rated as moderately to highly susceptible (>60% incidence) (Anahosur 2001). The Ute Russet cultivar, released in 1986, is considered resistant to S. rolfsii (Holm et al, 1987). Voss et al (1984) reported on some cultivars and breeding lines that were at least partially resistant.…”
