초록

본 시험은 고랭지에서 착색단고추의 접목재배로 토경재배시 지하부 환경개선을 통해 토양전염성 병을 예방하고, 수량성을 향상시키고자 저항성 대목들을 수집하여 접목재배하여 생육, 수량 및 병저항성을 비교하였다. 접수는 적색계인 스피리트품종을 사용하였다. 역병균을 접종한 결과 자근묘인 Spirit는 접종 후 5일 만에 100% 고사하였고, 저항성이 높은 대목으로는 탄탄대목, Skurt-S, AC 2258, PST 8301 등 4품종이었다. 또한 청고병에 저항성이 높은 대목으로는 역강, 탄탄대목, TE 412, 갤럭시, MC 4, PST VK, PST NV 등 7품종이었다. 접목구는 지근묘에 비해 근중이 무거워 지하부의 환경개선효과가 뚜렷하였다. 접목과 비접목에 따른 과실의 외적 ${\cdot}$ 내적인 품질은 큰 차이가 없었다. 수량성이 높은 대목은 PST 8301, MC 4, 왕건 등이었다.

This experiment was conducted to screen the suitable rootstocks for the soil cultivation of paprika (Capsicum annuum L.) in highland. Sixteen kinds of rootstocks were grafted to the red colored 'Spirit' scion for the resistances to diseases like fruit lot (Phytophthora capsici) and bacterial wilt (Ralstonia solanacearum). Four varieties among the rootstocks, 'Tantandaemok', 'Skurt-S', 'AC 2258', and 'PST 8301' were selected for the high resistance to fruit rot of paprika. However non-grafted control plants were totally dead at five days after inoculation. Furthermore, seven varieties including 'Yeokgang', ;Tantandaemok', 'TE412', 'MC 4', 'PST VK', and 'PST NV' were selected for the high resistance to bacterial wilt. The grafting with pest resistant rootstocks could enhance the rhizophere environment through root fresh weight increase. High yielding rootstocks for paprica 'Spirit' were PST 8301, MC 4, and Wanggeun.
