Abstract

Ninety two pepper (Capsicum annuum L.) cultivars were screened for resistance to two common species of root-knot nematodes, Meloidogyne incognita and M. arenaria. All 92 pepper cultivars were resistant to M. arenaria (0-3 eggmass/plant) but were susceptible to M. incognita (76-678 eggmass/plant). Susceptibility to M. incognita were slightly differed; 'Geomok' and 'Shintaepung' had relatively less eggmass (<100 eggmass/plant) when compared to those 29 very susceptible culivars such as 'Bulggotcheoreum' (>300 eggmass/plant). Therefore, pepper is highly recommended as a high-valued rotation crop to only those greenhouses infested with M. arenaria, but should restrict for M. incognita.

국내에서 시판되고 있는 고추 92품종을 이용하여 국내 시설재배지에서 가장 많이 분포하고 있는 두 종의 뿌리혹선충, Meloidogyne arenaria와 M. incognita에 대한 저항성을 검정하였다. M. arenaria에는 시판 고추 품종 모두가 저항성이었으며(난낭수 0-3/plant), M. incognita에는 모두 감수성이었다(난낭수 76-678/plant). M. incognita에는 모두가 감수성이었으나 품종별로 약간의 차이는 있었는데 거목(동부한농)과 신태풍(명산종묘) 2품종은 난낭이 포기당 100개 이하로 발생되어 불꽃처럼(누넴종묘) 등 29품종의 포기당 난낭수 300개 이상에 비해 상대적으로 적었다. 뿌리혹선충 피해가 심한 시설재배지 중에서, M. arenaria가 감염된 농가에서는 윤작작물로 고추를 심는 것을 적극 추천하고 반면, M. incognita가 감염된 포장에 고추는 윤작작물로 적절하지 않다.
