초록

The sugar beet cyst nematode (SBCN), Heterodera schachtii is a well known pathogen on Chinese cabbage in thehighland fields of Korea. However, recent reports have shown a coexistence of SBCN with the clover cyst nematode,H. trifolii in Korea. This study aimed at detailing and reviewing morphological and molecular characteristics conceivablyessential in differentiating the two nematode species. A comparison of morphometric measurements of both infective juvenilesand vulval cones of cysts showed significant differences between the two cyst nematodes. Indeed, using assorted cystsfrom field populations for molecular analysis resulted into a mixture of bands after gel electrophoresis, indicating a combinationof the two species. Thus, this study confirms the coexistence of the two species on Chinese cabbage fields in Korea.
