국내 콩 씨스트선충의 HG type 분석

Thirteen soybean cyst nematode (SCN) (Heterodera glycines) populations collected in Korea were examined in their HG type by their reproductivity on 7 Plant Introduction indicators for the identification of HG type. Six HG types were identified, HG type 0, 2, 5, 2.5, 1.2.7, and 2.5.7. HG type 2.5 was...

Zusammenfassung:Thirteen soybean cyst nematode (SCN) (Heterodera glycines) populations collected in Korea were examined in their HG type by their reproductivity on 7 Plant Introduction indicators for the identification of HG type. Six HG types were identified, HG type 0, 2, 5, 2.5, 1.2.7, and 2.5.7. HG type 2.5 was the most frequent (4 samples, 30.8%), followed by HG type 2.5.7 (3 samples, 23.0%). About 76.9% of SCN populations were reproduced on PI 88788, followed by PI 209332 (61.5%), PI 548316 ('Cloud') (30.8%), and PI 548402 ('Peking') (7.7%). No population could reproduce on PI 90763, PI 437654, thus, they could be used for resistant source for developing SCN resistant soybean in Korea. 콩 저항성품종 육성의 기초자료로 이용하고자 국내 13개 콩 씨스트선충 집단을 대상으로 HG type를 조사하였다. 국내 콩 씨스트선충 HG type는 0, 2, 5, 2.5, 1.2.7, 2.5.7로 총 6개의 HG type가 발견되었다. 그중 HG type 2.5가 30.8%로 가장 많았으며 다음으로 HG type 2.5.7(23.0%)이었다. 각 indicator별로는 PI 88788 가해 집단이 76.9%, PI 209332 가해 집단이 61.5%, PI 548316('Cloud') 가해 집단이 30.8%, PI 548402('Peking') 가해 집단이 7.7%였고 PI 90763, PI 437654, PI 89772를 가해할 수 있는 콩 씨스트선충 집단은 없었다. PI 90763, PI 437654, PI 89772은 국내 모든 콩 씨스트선충 집단에 대해 저항성으로 나타나 저항성품종 육성 교배 모본으로 이용될 수 있을 것이다.
