Abstract
Protoplasts were isolated from anther-derived suspension cultures of commercial wheat (Triticum aestivum L. cv. Chris). The protoplasts were released enzymatically and isolated by centrifugation on a sucrose cushion. The isolated protoplasts were initially cultured in a liquid medium in the dark. Numerous microcalli were produced under these conditions, some of which differentiated into globular embryos. Upon transfer to a solid medium and exposure to 16h/8h light/dark cycle, the protocalli proliferated and many of the somatic embryos matured. Complete plantlets were obtained and maintained in sterile culture.
