Optimum conditions were established for the regeneration of shoots from shoot tips, for daughter shoot formation and rooting as well as for the adaptation of the regenerated plants to the open ground. Gene banks of valuable clones were built by keeping shoots at 4°C on media with high sucrose concentration (maximum period of storage 2 years) or by growing juvenile clone plants in the greenhouse at temperatures preventing the induction of flowering. The clone plants were in the juvenile state even if they were derived from flowering mother plants. They showed normal growth and development.
