Abstract
Protoplasts were released from embryogenic suspension culture of Paspalum scrobiculatum and cultured in either liquid or semisolid KM medium supplemented with 2,4-D in the dark at 24°C with or without a feeder layer. Cell wall formation was observed in 75% of the plated protoplasts. Microcolonies developed after 10 d of culture, which in turn formed callus upon transfer to M-2 medium (Nayak and Sen, 1989). The highest plating effeciency (ca 7%) was obtained in thin-layer liquid culture. The macrocalli formed somatic embryos which regenerated to plantlets. The plantlets were grown to flowering plants upon transfer to soil.
