초록

고추 (Capsicum annuum L.)의 일대잡종을 이용하여 모본의 유전자형 및 생태형이 약배양 효율에 미치는 영향을 조사하였다. 모본의 유전자형에 따라 약배양 효율에 차이를 보였다. 또한 약배양 효율은 모본으로 배 발생률이 낮은 계통보다 높은 계통을 사용한 교배조합에서 높아 약배양 효율에 세포질 효과가 있는 것으로 나타났다. 또한 생태형에 따른 배 발생 효율은 재래종$\times$피망 교배조합에서 배 발생률이 17.8~46.1%로 가장 높았고, 피망$\times$재래종 조합은 5.4~8.5%의 배발생률을 보여 가장 낮았다. 재래종 $\times$남방계, 남방계 $\times$재래종, 남방계 $\times$피망, 피망 $\times$남방계 교배조합의 배 발생률은 10.5~23.1%로 비교적 중간값을 보였다.

The influence of genotype and ecotype on the anther culture efficiency using hybrid of hot pepper (Capsicum annuum L.) was investigated. Anther culture efficiency was differently dependent on the genotype of parents. In the efficiency of embryo production, the cross combination using female parents with high embryo inducing ability was higher than those with low embryo inducing ability. It was shown that genotype and cytoplasm has effect on embryo production. Also the embryogenic ability was different according to ecotype of cross lines. The frequency of embryo production were the highest in Local variety $\times$ pimento cross combinations with 17.8~46.1 and the lowest in Pimento $\times$ Local variety cross combinations with 5.4~8.5%. Embryo inducing frequency was the middle value with 10.25~23.1% in Local variety $\times$ Tropical variety, Tropical variety $\times$ Local variety, Tropical variety $\times$ Pimento, and Pimento $\times$ Tropical variety cross combinations.
