1. (1) Foundation caneberry plants must originate directly from nuclear stock and may be grown in a greenhouse, screenhouse or field.

   1. (a) The micro-propagated plants are isolated at all times from all other caneberry plants, except those that have been indexed and found free of virus or virus-like infections; and
   2. (b) The micro-propagation facility is approved by the department.
3. (3) Growers may transplant micro-propagated foundation plants to a greenhouse or screenhouse for conditioning prior to planting them in a foundation field.
4. (4) Foundation plants may be harvested from a foundation field planting for no more than one year.
5. (5) Foundation plants grown in an insect-proof facility in approved soil-less media may be maintained indefinitely, providing they are indexed and found free of virus or virus-like infections at intervals of no more than three years by personnel employed by the United States Department of Agriculture or other institution approved by the department.
6. (6) Each foundation plant in a foundation greenhouse or screenhouse must be grown in a container individually identified by the cultivar and lot.
7. (7) Different cultivars planted in a foundation field must be separated by a distance of fourteen feet or by a physical barrier that prevents the intermingling of roots.
