Abstract
Each of 48 monoconidial isolates of Colletotrichum gloeosporioides Penz. obtained from diseased fruits of pepper was classified into strain G or strain R based upon pathogenicity to green and red fruits, morphology of conidia, and cultural characteristics in potato dextrose agar. The strain G was designated for isolates to cause anthracnose symptoms both on green and red fruits. All isolates of the strain G produced conidia abundantly. but produced no perithecia and setae in PDA. Conidia of all isolates in the strain G were attenuated or round at one end. The optimum temperature for mycelial growth of strain G was
고추탄저병 이병과에서 분리한 Colletotrichum gloeosporioides Penz.의 48개 단포자분리균주를 풋소추와 붉은 고추에 대한 병원성, 분성포자의 형태, PDA배지에서의 배양적 특성에 다라 계통G와 계통R로 분류하였다. 풋고추와 붉은 고추에서 탄저병징을 일으키는 계통 G의 모든 균주들은 PDA배지에서 분생포자를 많이 형성하였으나, 자양각과 강모는 전혀 형성하지 않았다. 계통 G에 속에서 모든 균주들의 분생포자는 한쪽 끝이 좁거나 둥글었다. 계통G의 균사생장 적온은
