Abstract
Quantitative differences in pathogenicity of monoconidial subcultures of Pyricularia oryzae Cav. were examined. The subcultures had been isolated from a susceptible-(STL) and an intermediate type lesion (ITL), which originated from a single culture. The majority of the STL monoconidial subcultures produced more susceptible type lesions than did the ITL subcultures. The production of intermediate type lesions was similar in both groups of subcultures, whereas the ITL subcultures produced a high number of resistant type lesions. Within both groups, there was also some variation in numbers of lesions produced.
벼도열병균의 한 균주를 벼에 접종했을때 형성된 이병성병반 및 중도형병반에서 얻어진 단포자분리균주간의 병원성의 양적차이를 온실에서 조사하였다. 단일이병성병반에서 분리된 대부분의 단포자분리균은 단일중도형병반에서 분리한 균주보다 이병성병반형성율이 현저히 높았고 중도형병반 형성은 비슷하였다. 특히 중도형병반에서 분리한 균주가 저항성병반을 더 많이 형성하였다. 이들 두 단포자분리균주내에서도 형성된 병반수에 다소의 변이를 보였다.
