The aim of this study was to determine the resistance of some genotypes with different origins against Verticillium wilt. The study was conducted in randomized complete block design with three replicates in controlled growth chamber. Cotton seedlings in 2-3 true leaf stage were inoculated with 10(7) conidia ml(-1) spore suspension of V. dahliae which is leaf defoliating T-1 pathotype by root dip technique. The differences between disease indexes from leaf and vascular tissues were significant (P <= 0.01). Genotypes used in this study were categorized into 13 groups for leaf symptoms and 16 groups for vascular symptoms. Tamcot Camd-ES (1.39) from USA, PG 510-7 (1.64) and BA-525 (1.72) from Turkey were most resistant based on leaf symptoms. However, Tamcot Camd-ES (1.31) from USA, PG 510-7 (1.47) and IH-26-K-5 from Turkey were the most resistant genotypes based on vascular symptoms. In this study a high positive correlation (r=0.972) was found between diseases indexes from leaf and vascular tissues.
