Abstract

For management of soybean parasitic cyst nematodes, this study was conducted to investigate the resistance of the Korean soybean cultivars to HG type 2.5.7 of Heterodera sojae. Among the 44 Korean soybean cultivars, there was only one resistant cultivar ‘Namcheon’. ‘Sobaeknamul’, ‘Socheng No. 2’, ‘Pungsannamul’, ‘Cheongja’, ‘Miryang’ and ‘Daewon’ were moderately resistant to HG 2.5.7 of H. sojae populations. Eleven cultivars including ‘Paldal’ were moderately susceptible and the other cultivars were susceptible. Therefore, soybean cultivar ‘Namcheon’ should be cultivated in H. sojae infested fields, until varieties resistant against Heterodera species are more developed or identified. Moreover, ‘Namcheon’ is not recommended for cultivation because very weak to soybean mosaic virus, and it will be a candidate with resistant cultivar breeding resource.
