Fremont Mandarin

Fremont is a mandarin hybrid of Clementine and Ponkan made by P. C. Reece at USDA Orlando. UCR and IDtools report first fruiting at Brawley, selection by J. R. Furr at Indio (selection year not established), and release in 1964.^⁠[1]⁠[4]

Hodgson’s cultivar description, reproduced by UCR, describes medium, oblate fruit with smooth, bright reddish-orange rind and deep-orange, tender, juicy flesh. It reports moderately numerous small-to-medium seeds, about half monoembryonic, and ripening between Clementine and Dancy, with quality retained past maturity. That account describes the rind as readily peelable; the nursery video describes it as tight-skinned.^{⁠[1]⁠[4]⁠[9]}

UCR describes Fremont trees as moderately vigorous and upright, with few thorns, early bearing, and good productivity. Its account warns that an open canopy can leave fruit exposed to sunburn.^⁠[1]

Trial findings vary by study setting. At Dörtyol, Turkey, Fremont pollination treatments produced differing fruit-set and mean-weight results, and a separate leaf study found a seasonal carbohydrate low in August. In hot-arid Bikaner, India, Fremont scion growth and yield were greatest on Karna khatta, while Fremont on Pectinifera rootstock matured earliest. These are treatment- and site-specific findings.^{⁠[2]⁠[3]⁠[5]}

A postharvest study of Fremont IAC 548 at Cordeirópolis reported fruit from three-year-old Fremont trees grafted on Rangpur lime averaging 125.5 g and 11.16 °Brix. Fruit held at 8 ± 2°C and 90 ± 5% relative humidity retained acceptable physicochemical and sensory quality for 30–35 days; wax-coated refrigerated fruit received better panel ratings through day 35. A separate 50-person consumer survey reported 69% approval for fresh fruit and 79% for juice. These are study-specific storage and acceptance findings, not tree cold-hardiness or taste-intensity ratings.^⁠[7]⁠[8]
