“…These cultivars comprised approximately 98% of cotton plantings in Turkey in 2007 (Göre et al 2009). Treatments were applied in plots that were 0.7 m wide (in two rows of approximately 60 plants per row) by 12 m long in a randomized complete block design (with 2-m intervals between blocks) with four replicates (Erdoğan and Benlioğlu 2010).…”

“…The pathogen infects roots, causing foliar wilt and defoliation. Disease severity depends on several factors, including the cultivar used, the phenological stage of the plant, environmental conditions, inoculum density in soil, and the virulence of V. dahliae strains (Göre et al 2009). It was first reported in Turkey in 1941 (İyriboz 1941), but was not identified as an important disease under field conditions until 1967 (Karaca et al 1971).…”

Twenty-nine cotton genotypes with varying levels of susceptibility to Verticillium dahliae were grown in infested plots at Nazilli, Aydın, in 2008Aydın, in -2009. The highest level of disease incidence was recorded in cultivars 'BA-151', 'Celia', 'Çukurova-1518', 'Flaş' and 'Maraş 92', and averaged 85-95% for all genotypes in both years. The incidence of V. dahliae in seed averaged 29.8% for cv. Çukurova-1518, 27.6% for Flaş, 24.6% for cv. BA-151, 19.0% for cv. Celia and 16.2% for Maraş 92. Two hundred seeds from each genotype were planted, two seeds per pot, in a steam-pasteurized mixture of soil, peat, and sand. Pots were placed close to each other on a greenhouse bench to obtain a thick canopy. Typical disease symptoms appeared about 12-13 weeks after sowing. Maximum disease incidence values averaged 3.3% for Celia, 4.5% for Maraş 92, 8% for BA-151, 9% for Flaş and 9.5% for Çukurova-1518.

“…In previously conducted studies, it has been reported that cotton cultivars showed susceptibility to both pathotypes of V. dahliae at different levels. In result, most of the cultivars were very susceptible to defoliating pathotype in the growth chamber conditions, and the cv Carmen was resistance to both pathotypes at different levels (Göre et al, 2009;Erdoğan and Kurt, 2013;Erdoğan et al, 2014;Erdoğan et al, 2015).…”

Verticillium Wilt Disease is one of the most important diseases affecting the rate of cotton yield. There is no economic chemical control for Verticillium wilt, but it is recommended to use resistant varieties to control this disease. This experiment was carried out in a randomized plot design with four replications in the growth chamber to determine the response of some cotton cultivars against a defoliating and non-defoliating pathotypes of Verticilllium dahliae Kleb. In the study, a total of twenty cotton cultivars i.e. the resistant control GIZA 75, the tolerant control CARMEN and the susceptible control ACALA SJ2, defoliating (PYDV6 isolate) and non-defoliating (Vd 11 isolate) pathotypes were used, and cotton varieties were tested using conidial suspension technique. Analysis of variance showed significantly (P<0.05) differences among cotton cultivars. The lowest disease severity for the defoliating pathotype was determined in the resistant control GIZA 75 (1.00), followed by the tolerant control CARMEN (1.75) and FAMOSA (1.87). The highest disease severity was determined in the susceptible control ACALA SJ2 by 3.50 and BEREN by 3.12. The lowest disease severity for the nondefoliating pathotype was again determined in the resistant control GIZA 75 by 0.35, followed by the tolerant control CARMEN and GAIA. The highest disease severity value was again found in the susceptible control ACALA SJ2 by 2.50 followed by BEREN 2.12. As a result, cotton cvs FAMOSA and GAIA were tolerant to Verticillium wilt and BEREN was found to be susceptible.

“…Moreover, planting resistant varieties is a possible strategy for protection of cotton from V. dahliae, but few upland cotton cultivars showed resistance towards Verticillium wilt (Bolek et al, 2005;Gore et al, 2009;Gao et al, 2011).…”
