Abstract

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.
