This article addresses the studies on the resistance of cotton varieties to Verticillium dahliae Kleb on an artificial infectious background. It is shown that resistance indicators depend on the origin of varieties. V.dahliae isolates isolated from varieties C-6524, Namangan-77, Barkhayot, Shodiyona, Omad and C-8290 showed different virulence; isolates allocated from varieties C-6524, Namangan-77, Barkhayot, Shodiyona and Omad showed the highest virulence.
