To investigate physiological characteristics and genetic diversity of Rhizina undulata isolates distributed in Korea, cultural characteristics and random amplified polymorphic DNA (RAPD) of 13 Rhizina undulata isolates from Pinus densiflora and P. thunbergi stands were analyzed. There were no correlations between the host species of R. undulata isolates and the mycelial growth of R. undulata isolates on culture media supplemented with water-soluble extract from the two different host species, i.e., Pinus densiflora and P. thunbergi. Genetic diversity of genomic DNA from 13 R. undulata isolates was analyzed by RAPD using 12 random primers. There was no differentiation in RAPD profiles among the isolates from Korea. But, there was some differentiation in RAPD profiles between Korean isolates and Japanese isolates, with 88% homology by phylogenetic tree analysis.
