The susceptibility of cotton genotypes obtained from F6 and F7 generations to Verticillium wilt (VW) disease (Verticillium dahliae Kleb.), was studied under artificial and natural infestation during 2009 and 2010 growing seasons at the Cotton Research Institute’s, Nazilli, Aydın, Turkey. In this study, fifteen cotton breeding lines and two control varieties were used as plant material. During the cotton growing season, foliar disease index (FDI), vascular disease index (VDI) and pot disease index (PDI) were observed in addition to seed cotton yield and some fiber quality characteristics. According to the obtained results, disease severity (DS) values observed in pot experiments were higher than field trials. In terms of DS, ‘Tamcot CD3H’ × ‘Tamcot Luxor-III’, ‘Maraş92’ × ‘Tamcot Sphinx’ and ‘Sayar 314’ × ‘Stoneville 453-I’ breeding lines exhibited similar values with tolerant ‘Carmen’ variety. ‘Tamcot CD3H’ × ‘Tamcot Sphinx’, ‘Sayar 314’ × ‘Stoneville 453-I’, ‘Sayar 314’ × ‘Stoneville 453-II’ and ‘Stoneville 453’ × ‘Tamcot Sphinx’ breeding lines which gave similar DS values with tolerant ‘Carmen’ variety were statistically on the same group with ‘Carmen’ variety suitable to seed cotton yield. In this study, the disease tolerant breeding lines had higher fiber strength values than susceptible lines, the lowest fiber strength value obtained from ‘Cukurova 1518’ susceptible variety.

Varietal differences in susceptibility (as assessed by the proportion of affected plants) to wilt of cotton caused by Verticillium dahliae Kleb., were observed in south-eastern Queensland. The progression of the disease within individual plants, however, was similar in all varieties. Deltapine Smoothleaf, the most widely grown variety in Queensland was one of the most susceptible varieties. Derivatives of Rex or Dixie King were less affected. The disease caused a difference in yield between healthy and diseased plants which could be as high as 30 per cent.

Screening of upland cotton genotypes against Verticillium wilt disease was conducted. The 268 upland cotton genotypes (Carmen and Acala Maxxa cultivar were tolerant- control while cvs. Cukurova 1518 and Acala SJ2 were susceptible-control) were screened against defoliating (PYDV6) and non-defoliating (Vd11) pathotypes of the fungus in a randomized plot design with four replications in growth chamber. Field experiment was established according to the augmented experimental design. Variance analysis was significant (p ≤ 0.05) for all traits against Verticillium wilt. Cvs. Semerkant Uzbek and Taskent 6 were more tolerant than the tolerant-control cultivars against both pathotypes. Most of the genotypes were tolerant in field trial in terms of disease severity that was the lowest for STN K311 genotype in both periods. The highest seed cotton yield was obtained in genotypes as BA119, Okra 204, H-23, Gedera-5, PI 528420 and Acala Royale, which were moderately tolerant to the wilt disease.
