After the recent detection of serious losses caused by Verticillium wilt of cotton, incited by the defoliatingpathotype of Verticillium dahliae in the Aegean Region of Turkey, 28 of the most commonly grown cottoncultivars (Gossypium hirsutum L.) of Turkey, were evaluated for the presence of field resistance to wilt.Six-week-old plants were inoculated with a cotton nondefoliating (ND) or a cotton defoliating (D)pathotype of V. dahliae under controlled conditions. Resistance was evaluated on the basis of externalsymptoms by calculating areas under disease progress curves. The percentage of plants killed and ofthose which recovered from the disease was used as additional parameters for including a particularcultivar into a defined category. Most of the evaluated cultivars were susceptible, although at differentlevels, to both pathotypes of V. dahliae. All cultivars were more susceptible to the D than to the NDpathotype. The most promising cultivars in the experiments appeared to be Carmen and ST-373. Carmenshowed differential resistance: it was susceptible to the D but resistant to the ND pathotype. ST-373 wasmoderately susceptible to both pathotypes of V. dahliae. A resistance related phenotypic reaction to thedisease was quantified by using six growth parameters (plant height, number of nodes, leaf weight, stemweight, leaf to stem ratio, and total shoot weight) measured 13 d after inoculation. The percentagedecrease in leaf–stem ratio and leaf weight were found to be the best indicators of resistance. Resultsobtained in this study will be useful to quantify resistance to V. dahliae and identify the best parametersto phenotype in genetic studies.
