ABSTRACT
This study was conducted to determine the susceptibility of 15 clones of native and foreign poplar species and their hybrids to Melampsora leaf rust and to select resistant clones at a nursery stool bed. Rust severities of individual trees were determined by estimating the percentage of infected leaves on the trees in addition to comparing the infected leaves with the infection diagrams. Three hybrids out of 15 clones were selected as resistant clones to the Melampsora leaf rust in Korea. Bong-wha 1 and Hyunsasi 3 belong to section Leuce, and Dorskamp belongs to section Aigeiros. Based on our results, we recommend Dorskamp as the best resistant clone to poplar leaf rust.

적요

본 연구는 국내에 있는 자생포플러, 도입포플러, 교잡종포플러 15개 클론 삽목묘의 잎녹병에 대한 감수성을 규명하고 저항성 클론을 선발하기 위해 수행되었다. 각 개체별 잎녹병 피해도는 감염된 잎을 경, 중, 심으로 구분하여 일정한 점수를 부여한 후 한 나무당 감염된 잎의 비율로서 추정하였다. 실험에 포함된 15개 포플러 클론들 중 Dorskamp, 봉화 1, 현사시 3이 한국에서 만연하고 있는 Melampsora 잎녹병균에 저항성이 높은 클론으로 선발되었는데 이들 중 봉화 1과 현사시 3은 포플러 6개 절(section)중 Leuce 절에 속하고 Dorskamp는 Aigeiros 절에 속한다. 특히 Dorskamp는 외관상으로도 잎녹병에 감염된 잎이 현저히 적어 포플러잎녹병 저항성 품종으로 추천할 만한 클론인 것으로 확인되었다.
