Studies on the Host Selectivity and Pathogenicity of White Pine Blister Rust Fungus (Cronartium ribicola J. C. Fischer ex Rabenhorst) in Korea <Jour. Kor. For. Soc. 62:76-81 1983> Corresponding author khj5004@forest.go.kr
Pedicularis spp. are the alternate hosts of the white pine blister rust fungi in the forest of Korea, and Ribes spp. were found as other alternate hosts by artificial inoculation test. New biotypes (races) with different host selectivity and pathogenicity of the causal fungi were speculated at various places in Korea. The aeciospores of the fungi were collected from two isolated places, Pyeongchang and Namwoen, and artificially inoculated on Pedicularis resupinuta and six species of the genus Ribes. Among the tested alternate host species, P. resupinuta and R. monrigenum were only susceptible to both the Pyeongchang population and the Namwoen population, showing similar pathogencity between the two fungal populations. Three white pine species were planted in fungus-infested stands to study the susceptibility of each tree species. Four years later, 17.7% of Pinus koraiensis and 26.3% of Pinus strobus were infected, but Pinus pariflora was free from attack. From the above results, it was concluded that the white pine blister rust fungus populations in Korea are of the same biotype, with Pinus koraiensis and Pinus strobus as aecial hosts, and Pedicularis spp. and Ribes spp. as telial hosts.
Key words: Cronartiuin ribicola, host selectivity, pathogenicity
