The Dundee Foundation Grove combines an 80 acre field planting with greenhouses and screenhouses for the horticultural evaluation and distribution of virus free stock to commercial nurseries. The Foundation Grove is planted with 510 different clones representing 184 different citrus varieties. The field plantings utilize over 50 different rootstocks for comparison.
Horticultural evaluation is ongoing among differing varietal clones for production yields.
Two large screenhouses provide pathogen free budwood to nurserymen to establish new source tree plantings throughout the state. Greenhouses are used to conduct viroid indexing of grower source trees. The periodic testing of grower registered budwood sources ensure that nurserymen are using healthy clean stock to produce new nursery trees for the industry.
