The optimal conditions for the protoplast isolation from the leaves of pea (Pisum sativum L. cv. Sparkle) and barley (Hordeum vulgare L. cv. Baecdong) were determined in order to achieve a somatic hybridization between two species. It was revealed that the use of 0.5 M sorbitol as an osmoticum was appropriate for pea. The yield of intact protoplasts was highest (40%) when pea leaves were incubated in the enzyme solution for 4 hours. In the case of barley, the optimal concentrations oc cellulase, pectinase and mannitol as the enzyme solution were 2%, 1% and 0.35 M, respectively. The yield of barley protoplasts was highest (85%) when leaves were incubated in this enzyme solution for 3.5 hours. A fusion of protoplasts from pea and barley was induced by the PEG treatment enriched with calcium salts within 60 minutes.
