Tree health index data was collected from the following trials: IMG, Citra, Steve Brewer (Land-O-Lakes scion trial), Banack, Hidden Golf Course (multi-scion trial), Smoak, Wheeler Bros., Peace River, and Greene Citrus (lemon trial). All ‘gauntlet’ trees were scored for health index; large fruit size was noted on a few selections that also had exceptionally healthy trees. Tree size/canopy volume data was collected from the Orie Lee OLL clone/rootstock trial. Our field crew assisted with roof repairs to our certified greenhouses and to our repository; this was necessary to maintain their legal status as sources for pathogen-free trees to be planted across the state. Propagation of best ‘gauntlet’ rootstocks: Additional cuttings were produced from 3 promising SugarBelle hybrids and two S11 (salt tolerant Pummelo x Cleo) x trifoliate orange 50-7 hybrids. Two large grapefruit/rootstock experiments, including all of our PTP red grapefruit clones and new candidate rootstocks were planted with Bryan Paul citrus and English Bros. Citrus (many of the trees for the English Bros. trial were propagated by our team at the CREC, all others by Briteleaf Nursery).
