Cotton bacterial blight is one of the most important diseases of cotton in many cotton growing areas of the world. The symptoms of this disease may appear during the whole growth stage of the plant. Use of resistance cultivars is the main control measure against this disease to study the response of common commercial cultivars of cotton a experiment was carried out in 2005 as CRD in greenhouse condition of cotton Research Institute, Gorgan with 10 treatments and 4 replication. The treatments were Sahel, Varamin, Bakhtegan, Mehr, Tabladila, Crema, Nazily, No.200, Sepid (Siokra) and Khordad (Sindose) cultivars. The seeds of mentioned cultivars disinfected to 10% chlorax solution and sowed in pots containing sterile soil. The bacterial suspension in 106 cfu was inoculated to the cotyledons of emerged plants. Evaluation of disease progress based on concern index was started one week after treatment and continued to about one month later. The results revealed that the Sepid (Siokra) was resistance and other cultivars were susceptible to Xanthomonas axonopodis pv. malvacearum.
