Abstract

A total of 238 accessions of peppers (Capsicum spp.) were evaluated for resistance to powdery mildew (Leveillula taurica (Lev.) Arn) in 1998-1999. KC604, 605, 606 and 608 of C. baccatum, KC616 of C. chinense, and KC638, 640, 641, 642, 643 and 644 of C. pubescens were highly resistant and remained disease-free. KC47-1 (PI244670), KC319-1, KC545, KC320 showed only mild infection compared with susceptible control group, 'Chungok' and others. Therefore, they were considered moderately resistant. Among them, KC47-1, KC319-1 and KC320 are sources of resistance to gray leaf spot caused by Stemphylium spp. while KC47-1 is also resistant to bacterial leaf spot (Xanthomonas campestris pv. vesicatoria (Doidge) Dye). Therefore, they may be used in breeding for multiple resistance to those diseases.

1998-1999년도에 걸쳐 총 238점의 고추 유전자원에 대하여 흰가루병에 대한 저항성을 검정한 결과, Capsicum baccatum에 속하는 KC604, 605, 606, 608, C. chinense에 속하는 KC616, C. pubescens에 속하는 KC638, 640, 641, 642, 643, 644가 발병하지 않을 정도로 고도의 저항성을 나타내었으며 C. annuum에 속하는 KC47-1(PI244670), KC319-1, KC545, KC320는 경미하게 발병하여 다소 저항성으로 나타났다. KC47-1, KC319-1, KC320은 Stemphylium spp.에 의한 고추 잎점무늬병에 저항성이며, 그 중 KC 47-1은 더뎅이병(Xanthomonas campestris pv. vesicatoria)에도 저항성이어서 이들 병에 복합저항성 육성도 가능할 것으로 기대된다.
