| Abstract: | otyledon protoplasts of tomato (Lycopersicon esculentum L.) isolated from 2–3 week grown seedlings were cultured in MS liquid medium (2,4-D 1, 6-BA 0.1 mg/l) and fresh medium added subsequently. After 6 weeks culture, the cell clusters were transferred to semisolid medium (the additive same as in liquid medium, agar 0.3%). When the calli grew to 0.5 cm in diameter, transfer them to MS medium (6-BA 2, IAA 0.2 mg/l) for differentiation. The regenerated plants were obtained. After comparing different culture methods, tomato protoplasts grew better in double layers than in agar plate and hanging drops. |
