Fusarium verticillioides J. Sheldon infects a wide range of crops throughout the world. It has been isolated in corn of all endosperm types. Due to the cosmopolitan nature of F. verticillioides and its ability to survive in seed and debris, crop rotation and chemical control generally have been ineffective. Sweet corn inbreds have been identified that exhibit partial resistance to kernel infection by F. verticillioides and good emergence. We report preliminary information for future studies on the genetics of resistance in sweet corn to this seed-borne pathogen. Kernel infection by F. verticillioides was influenced by several factors, such as 1) endosperm mutation; 2) silk condition; 3) moisture content of the silks. Wide variation in kernel infection suggested that several genes might be involved for the partial resistance action.


Fusarium verticillioides J. Sheldon은 전세계적으로 여러 작물에 영양을 끼치는 걸로 알려 져 있다. 근래에는 대부분의 옥수수종류에 감염이 되는 것이 증명되었다. F. verticillioides의 광역적인 서식능력과 생식능력으로 인하여 물리적 화학적 조절이 어렵게 되었다. Sweet corn inbreds들 중 F. verticillioides에 부분 저항성이 있고 발아력이 좋은 inbred들이 존재함이 증명 되었다. 본 실험에서는 sweet corn을 토대로 한 저항성 유전 연구를 위한 기초 자료를 논하였 으며, F, verticillioides에 의한 종자 감염이 1) 배유종류 2) 옥수수 수염상태 3) 옥수수 수염의 수분 함량 등에 영향을 받았다. 종자 감염에 있어서 큰 변이를 보임은 여러 유전자들이 부분적 저항성에 영향을 줌을 알 수 있었다.
