Abstract

국내에서 육성된 75개 콩 장려품종에 대하여 콩 씨스트선충 HG type 2.5에 대한 저항성을 검정하였다. 품종에 따라 콩 씨스트선충의 증식 정도는 104-624 씨스트/화분이었다. 국내 콩 장려 품종 중에서 콩 씨스트선충 HG type 2.5에 대한 저항성 품종은 없었으며, '장엽콩', '새알콩', '밀양콩', '만석콩'은 중간저항성, 33품종은 중간감수성, 나머지 38품종은 감수성으로 판정되었다. 국내에서 저항성 장려품종이 육성되기까지 콩 씨스트선충의 피해가 심한 포장에는 '장엽콩', '새알콩', '밀양콩', '만석콩'을 심도록 추천하는 것이 좋겠다. A total of 75 soybean cultivars developed in Korea was screened against soybean cyst nematode (SCN), Heterodera glycines HG type 2.5. Cysts developed on soybean cultivars ranged from 104 to 624 cysts per pot. There was no resistant cultivar but 'Jangyeopkong', 'Saealkong', 'Miryangkong', and 'Mansukong' were moderately resistant; 33 cultivars were moderately susceptible and the other cultivars were susceptible. 'Jangyeopkong', 'Saealkong', 'Miryangkong', and 'Mansukong' could be recommended for soybean fields infested with SCN until developing SCN resistant soybean.
