고추 자엽에서 식물체 재분화의 품종간 차이 = Varietal Difference in Plant Regeneration from Cotyledon Culture of Capsicum annuum L.

국문 초록 (Abstract)

자엽으로 부터 신초 유기율은 MS기본배지와 MS기본배지에 IAA 0.25mg/L 또는 0.50mg/L과 zeatin 2.0mg/L 또는 4.0mg/L를 단독 및 조합 처리한 배지중에서 M배지에 IAA 0.25mg/L + zeatin 2.0mg/L 첨가된 배지가 63%로 가장 양호하였다. 신초 유기시기는 품종 및 배지에 따라 치상후 9~25일의 차이가 있었는데 MS배지 + zeatin 2.0mg/L + IAA 0.25 mg/L배지에서 영양재래, 풋고추, 342, Kakovskij-A-35, Gris I-A-1가 빠르게 유기 되었으며, MS배지 + BA 2.0mg/L + IAA 1.0mg/L 배지에서 COO485 Long Hot P5-3, Gris I-A-1에서 유기가 빨았다. 신초 유기율도 품종 및 배지에 따라 달랐는데 MS 배지 + zeatin 2.0mg/L + IAA 0.25mg/L 배지에서는 621, 영양재래, Nikko(일광), 적색물고추, Ch-6Num-216, 풋고추, Kakovskij-A-35가, MS배지 + BA 2.0mg/L + IAA 1.0mg/L 배지에서는 Fresno Chile, PI 169126, 적색물고추, PI 297438가 90%이상으로 높았다.

Effects of genotype and culture medium on plant regeneration from cotyledon segments of red pepper(Capsicum annuum L.) was investigated. Among combinations of IAA(0.25 and 0.50 mg/L) and zeatin(2.0 and 4.0 mg/L) added to MS medium, combination of 2.0 mg/L zeatin and 0.25 mg/L IAA was shown to be the best for shoot differentiation from cotyledon segments. Shoot regeneration from cotyledon explants took 9 to 25days, depending on genotypes and culture media. Early shooting was observed in Yeongyangjaelae, Putgochw, Karkovskij-A-35, Gris I-A-1 on MS medium containing 2.0 mg/L zeatin and 0.25 IAA mg/L. Percent of explants producing shoots, as also influenced by genotypes and culture media, were over 90% for 621, Yeongyangjaelae, Putgochw, Nikko jacksacgmulgochw, Ch-6-Num-216, and Kajenskij-A-35 when cultured on MS medum supplemented with 2.0 mg/L zeatin and 0.25 mg/L IAA and for Fresno chile, PI 169126, Kajenskij-A-35, jacksacgmulgochw, and PI 297438 on MS medium including 2.0 mg/L BA and 1.0 mg/L IAA.
