Overall research objectives are to develop, evaluate and release improved citrus scion varieties for the US. Approaches utilized to generate novel germplasm include hybridization, irradiation and transformation. Material is evaluated for horticultural performance, fruit quality characteristics and postharvest behavior. Promising selections are propagated and evaluated in replicated field trials. Currently we have several new citrus scions targeted for release including a seedless 'Pineapple' and a low-seeded 'Fallglo' tangerine.
