Abstract/Contents:"Take-all patch (Gaeumannomyces graminis var. avenae, Gga) of creeping bentgrass develops in the spring and early summer in central USA. In northern Illinois, we have observed that the timing and severity of symptoms, and the effect of fungicides varies among locations. This raised the question as to whether sub-varietal groups of Gga exist. Random amplified polymorphic DNA (RAPD) analysis using a single primer (OPA-02) was used to investigate genetic variation among 51 isolates of Gga collected from two golf courses (OV and NC) in Illinois. Using the unweighted pair group method with arithmetic mean (UPGMA), the isolates from the NC location were clustered into four groups .The genetic distances within this group ranged from 0.01 to 0.47. Isolates from the second location (OV) were sub-divided into three different groups (OVa, OVb, and OVc), as these represented three distinct areas separated by over 300 m. UPGMA clustered these isolates into one main cluster. The majority of isolates from area OVa separated into one main group, while the isolates from areas OVb and OVc grouped together into 4 subgroups. The genetic distances ranged from 0.001 to 0.52. These results show that by using a single primer, polymorphism can be demonstrated amoung populations of Gga that are separated by short distances; even though Gga has been reported to occur throughout the temperate climatic zone."
