This study was carried out at the experimental  fields of the Nazilli Cotton Research Institute between 2008 and 2009. The aim  of the study was to determine the reactions of the new cotton genotypes which were  developed at the Institute to verticillium wilt disease and to evaluate yield  and some fiber quality parameters. For this reason, all mid-long thirteen  cotton genotypes including Çukurova 1518 susceptibile, Aydın 110 standard and  Carmen varieties tolerant were first evaluated for reactions to Verticillium dahliae Kleb. in pot trials  at growth room. And then the field experiment was conducted in a randomized  complete block design with four replicates in naturally infested field with  cotton wilt disease and background of V.  dahliae inoculum (69 ms/g). Results of growth room studies showed that  diseases intensity value higher than field experiments. The results indicated  that differences among cotton genotypes were found significant for all of the  investigated characteristics. Among the genotypes which were tested in years  2008 and 2009, 1011 (0.74), 211 (0.78), 305 (0.79) and 405 (0.79) cotton  genotypes were determined most tolerant than the other long fiber cotton  genotypes. As a seed cotton yield, the genotypes of 1001 (336.5 kg/da) was the  least yield while 211 (417.6 kg/da), 405 (416.8 kg/da) and 305 (414.9 kg/da)  genotypes were found to be higher yield. The cotton genotypes 607 (32.9 mm),  408 (32.8 mm) and 305 (32.6 mm) were found to be the best fiber quality  properties.
