Abstract
Lines bred for resistance to Phytophthora capsici by incorporation of resistance to P. capsici in PI201234 or CM334 into 'Subi' and 'Chilseong', land races in Youngyang, and 'Punggak', a land race in Cheongdo in Gyeungbuk province, and lines bred for fortification of one of them above with resistance to viral complex, and tolerant selections from another landrace collection from Punggak (KC268) were evaluated for resistance to P. capsici by inoculation at seedling stage. Almost all the breeding lines showed high level of resistance to P. capsid and selections from KC268 showed tolerance or moderate resistance to P. capsid. The selected plants were grown in a net cage in an outdoor nursery for seed production. Utilization of the lines in breeding was discussed.
경북 영양지역 재래종인 수비초와 칠성초, 청도지역 재래종인 풍각초에 역병 저항성을 도입하여 육성한 계통, 이중 하나에 바이러스 저항성을 도입하기 위하여 육성한 계통, 풍각 재래종에서 선발한 역병 저항성 계통의 역병에 대한 저항성을 유묘접종으로 다시 평가하였다. 육성계통들은 모두 역병에 고도의 저항성을 나타내었으며, 풍각재래(KC268)에서 선발한 계통들은 중도의 저항성을 나타내었다. 선발개체들을 옥외 묘상에 심고 그 위에 방충망을 씌워 종자를 증식 채종하였다. 이틀의 육종적 활용방안에 대하여 논하였다.
