Abstract

Alfalfa plants are usually regenerated from protoplasts with an intervening callus stage (Johnson et al. 1981; Arcioni et al. 1982; Atanassov and Brown 1984; Pezzotti et al. 1984). Because considerable somaclonal variation could occur during callus development and growth (Bingham et al. 1988), direct embryogenesis, whereby the callus stage is bypassed or maintained for a very short period, appears to be advantageous in preserving genetic identity and reducing the time required for the operation, especially for protoplast fusion, microinjection, and direct transfer of specific genes to produce transgenic plants.
