This study was conducted in Kahramanmaraş  Agriculture Research Institute experimental areas between 2009 and 2010. The goals are  determinationthe susceptibility of cotton varieties and variety candidates,  were developed against Verticillium wilt disease by breed studies furthermore  cotton varieties, were brought from abroad and registered in Turkey, against  wilt disease, and determining yield and some lint quality features of  varieties. It was conducted with 13 cotton varieties with randomized  complete blocks design with three replicates in areas, were naturally  contaminated with Verticillium wilt disease. Wilt infection counting was  determined from leaves at 5-10 % and 50-60 % boll opened period of cotton  varieties and accessions. Finally, it was determined from stem cuttings at  after harvest, using 0-3 scale. It was determined that; cotton varieties  displayed important differences in terms of features analyzed in this study.  Disease counting results; the variety Teks was determined as the most tolerant  and followed by GSN-12, ST-468, Ayhan-107, BA-525 respectively. The variety  Çukurova-1518 placed in the most susceptible disease group and followed by  DP-388, Ekşi-911, Menderes-2005 respectively. The variety Çukurova-1518 was  caught wilt disease an early period and was found to be as susceptible, gave  the lowest yield value. It was observed that; wilt disease particularly had an  effect on yield, decreasing the fiber maturity and increasing the short fiber  index, furthermore negligible level of negative correlation was observed  between wilt disease and fiber length, strength, fineness.
