In this study, the variation of 20 Pinus thunbergii isolates of F. circinatum from 2 damaged sites in Jeju-Island were
compared with a known Fusarium circinatum using molecular biological techniques. Two- and four-year-old seedlings of Pinus
rigida×Pinus x rigitaeda and two-, three- and six-year-old seedlings of P. thunbergii were inoculated with one of the most
virulent isolates, FT-7, to determine differences in susceptibility. In site 1 (FT), 13 isolates of F. circinatum were isolated from
14 individuals and in site 2 (FS), 7 isolates of F. circinatum were isolated from 9 individuals. No difference was found in the
sequences of the internal transcribed spacer (ITS) region of the ribosomal RNA genes in the FS and FT isolates, and also even
in the known isolate of F. circinatum, FE 1-1. However, the ITS sequences of the FS and FT isolates differed from those of
a fungus, Botrytis cinerea. Two-year-old seedlings of P. rigida×P. x rigitaeda showed higher susceptibility (93.3% of mortality)
than four-year-old ones. Three-year-old seedlings of P. thunbergii showed the highest susceptibility (66.7% of mortality)
compared to those at other ages in the same species. We found a positive correlation between basal diameter and lesion length
in the seedlings of P. rigida×P. x rigitaeda (R2 = 0.66) and P. thunbergii (p < 0.0001), respectively. There were significant
differences in susceptibility by the age of seedlings in each of P. rigida×P. x rigitaeda (p < 0.0001) and P. thunbergii (p < 0.0001)
based on lesion length.
