In this research different isolates of fluorescent pseudomonads was provided and after investigation of their biochemical characteristics, and their ability to control take-all disease of wheat, their genetic diversity and relation between DNA fingerprinting and biocontrol ability of the isolates was investigated using rep-PCR molecular marker. DNA fingerprinting results and the drown dendrogram showed that19 fluorescent pseudomonads isolates differentiated in 25-100% genetic similarity level and the isolates belonged to nine fingerprinting groups assigned by letters A-I. Based on these results, there was a relation between DNA fingerprinting and inhibition zone, production of HCN and diacetylphloroglucinol production bioassays. Therefore, we suggested that rep-PCR molecular marker is a useful tool for identification and screening of fluorescent pseudomonads with biocontrol ability.
