‘CP 09‐1822’ (Reg. No. CV‐180; PI 686956) sugarcane (a complex hybrid of Saccharum spp.) was released in June 2016 for commercial cultivation on sand (mineral) soils in Florida. This cultivar was developed through a collaborative sugarcane cultivar development program of the USDA–ARS, the University of Florida, and the Florida Sugarcane League, Inc., based at Canal Point (CP), Florida. The parentage of CP 09‐1822 is CP 01‐2459 × CPCL 02‐8021. CP 09‐1822 had significantly greater mean stalk weight, tonnes of cane per hectare, tonnes of sugar per hectare, and economic index than the reference cultivars, ‘CL 88‐4730’, ‘CP 78‐1628’, and ‘CP 89‐2143’, in nine harvests with three crops (plant cane, first ratoon, second ratoon) at each of the three locations. Mean economic index or profitability of CP 09‐1822 was 21% higher than the second most common cultivar on sand soil, CL 88‐4730, and 36% higher than the other two reference cultivars. CP 09‐1822 is considered resistant to brown rust, orange rust, Sugarcane mosaic virus strain E, and Sugarcane yellow leaf virus , is moderately resistant to leaf scald and ratoon stunting disease, and is moderately susceptible to smut. CP 09‐1822 has the Bru 1 gene that provides resistance against brown rust. CP 09‐1822 ranked 9 among 32 tested genotypes for post‐freeze temporal sucrose deterioration and showed moderate to high freeze tolerance.
