Abstract

Verticillium wilt disease caused by Verticilium dahliae Kleb. is a major problem on cotton growing areas in Turkey. In the present study efficient differentiation by molecular markers on fluorescent Pseudomonas strains with antagonistic properties have been evaluated and tested in order to determine a possible correlation between their genetic diversity and the antagonistic effects to V. dahliae. Therefore. twelve RAPD markers showing high polymorphism ratios within fluorescent P. strains have been selected. The selected RAPD primers resulted in discrimination on selected antagonistic strains, displaying significant correlation with their antagonistic effects on suppressing Verticilium dahliae. Therefore the fragments produced after priming with selected RAPD markers can be suggested as a marker in selecting the effective antagonistic fluorescent P. strains to V dahliae.
