Frost resistance is an important trait in plant breeding. The cultivated potato Solanum tuberosum L. is reputed to be a frost-sensitive crop. Frost resistance was incorporated into cultivated potatoby protoplast fusion from a wild species S. commersonii Dun. The soluble proteins in leaves of asymmetric somatic hybrids of Solanum tuberosum and frost resistant S. commersonii were analysed. Differences of total soluble protein and chloroplast contents in frost resistant hybrids of potato were detected. These proteins were responsive to low temperature and may be play a role in frost resistance as representatives of the family of cold regulated proteins.

Key words: chloroplast, frost resistance, Solanum commersonii Dun., Solanum tuberosum L., soluble proteins.
