Abstract
Protoplasts were enzymatically isolated from leaves obtained from bulb cultures of amphidiploid A. wakegi, and protoplasts were inoculated in KM8P liquid medium containing 0.1M Mannitol, 0.4m glucose. 0.4mg/12,4-D, 2 mg/1NAA and 1 mg/1BAP, and incubated in dark. Colony formation was observed within two weeks of inoculation, and developed into mini-callus after one month. The minicallus obtained were transferred to MS medium containing 3% sucrose, 0.4 mg/1 2,4-D, 2 mg/1 NAA. 1 mg/1 BAP, and 0.8% agarose, and developed into friable callus.
