Abstract

Anthers from several lines of carrot (Daucus carota L.) were plated on the semi-solid B$_{5}$, basal medium supplemented with 2,4-D and NAA at two concentrations, 1.0 and 2.0 mg/L plus 0.2 mg/L BAP (benzylaminop-urine). Anthers of the most lines on the B$_{5}$ basal medium with 2,4-D showed higher percentages of callus formation than those with NAA. Particularly, in line 45477, highest percentages of callus formation (50%) were observed on B$_{5}$ medium with 1.0 mg/L 2,4-D plus 0.2 mg/L BAP. With 1.0 mg/L 2,4-D, two months was sufficient for initiation of callus development. Calli were regenerated into plantlets through embryogenesis onto regeneration medium without any growth regulators. When callus showing yellowish and soft structure was cultured, it yielded green plants at high regeneration rates, The response of anthers in callus induction and plant regeneration was different among lines investigated. Optimal callus induction and plant regeneration could be obtained through manipulating the concentration of growth regulators. Plantlets after transfer to perlite were grown successfully in greenhouse conditions. Anther culture of carrot will be used as a useful breeding tool in future.

본 연구는 당근에 있어서 유용한 육성재료를 순계화하기 위한 가능성을 찾기 위하여 약배양을 수행하였다. 캘러스를 유도하기 위하여 여러 계통의 약을 1.0 and 2.0 mg/L 2,4-D와 NAA가 첨가된 B$_{5}$ 반고체배지에서 배양하였다. 2,4-D가 함유된 배지가 NAA가 함유된 배지보다 캘러스 형성에 큰 영향을 미치는 것으로 나타났다. 특히 계통 45477의 경우 1.0 mg/L 2,4-D가 함유된 배지에서 약 50%의 높은 캘러스 형성률을 보였다. 두 달 정도 배양하면 충분히 캘러스를 유기할 수 있었다. BAP 또는 NAA 농도가 낮아질수록 식물체 생산에 효과적이라는 것을 알 수가 있었으며 식물생장조절물질이 전혀 첨가되지 않은 배지에서 캘러스를 배양하는 것이 기내에서 식물체 생산에 이상적이었다. 노랗고 부드러운 조직을 보이는 캘러스에서 식물체 분화율이 높게 나타났으며 약배양에 대한 반응은 계통간에 뚜렷한 차이를 보였다. 배지에 함유된 생장 조절물질을 조절함으로써 약으로부터 캘러스를 유기하거나 식물체로 분화시킬 수 있었다. 배양묘의 엽수에 관계없이 퍼얼라이트 배지에서 4주간 충분히 순화시킨 유식물체에서 포장 생존율이 100%로 가장 높았다. 지금까지의 연구 결과 한개의 캘러스에서 식물체를 대량으로 생산할 수 있었으며 이약배양기법이 당근 품종육성에 이용될 것으로 전망된다.
