Abstract

Pepper powdery mildew causes increasingly economical damage due to increased cultivation of pepper in greenhouses. To assess resistance of pepper resources against pepper powdery mildew, we developed a novel evaluation formula for pepper resistance against powdery mildew. The evaluation formula named S index is as follows; (number of the highest disease leaf/top leaf number)-(number of the lowest disease leaf/top leaf number). Positive correlation (81%, P = 0.01) between S index and authentic disease leaf rate was observed from the pepper plants infected by powdery mildew. Various pepper species from our genetic resources were evaluated to identify pepper varieties conferring resistance against powdery mild using S-index. Capsicum frutescens accessions 3CA131 and C. baccatum accessions 3CA0162, 3CA174, 3CA176 showed high resistance to powdery mildew, but none of C. annuum was resistant. Results suggest that S-index proposed in this study is useful to assess resistance evaluation of powdery mildew in chili pepper breeding.

고추 흰가루병은 시설재배의 증가로 경제적인 피해가 증가하는 병해이다. 본 연구에서는 고추 유전자원의 흰가루병 저항성 평가를 위한 새로운 저항성 평가 방법을 개발하였다. S index라고 명명한 평가방법의 공식은 다음과 같다; (최상위 발병 엽수/정단부 엽수) - (최하위 발병 엽수/정단부 엽수). 흰가루병에 의해 발병된 고추 식물체에서 이병엽율과 S index는 81%(P = 0.01)의 정의 상관으로 고도의 유의성을 보였다. 그리고 34종의 유전자원에서 저항성을 평가한 결과, S index는 흰가루병 저항성 계통을 구분할 수 있는 것으로 확인되었다. 이들 중 Capsicum frutescens 인 3CA131과 C. baccatum인 3CA0162, 3CA174, 3CA176은 흰가루병에 강한 저항성으로 평가되었다. 이 결과는 고추 흰가루병 저항성품종 육성에서 Sindex의 유용성을 증명한 결과이다.
