Interpretive Summary: The U.S. Department of Agriculture, Agricultural Research Service Washington, D.C.; the University of Florida, Institute of Food and Agricultural Sciences, Gainesville, FL; and the Florida Sugar Cane League, Inc., Clewiston, FL, working cooperatively to breed and select improved sugarcane cultivars, have jointly developed and hereby announce the release of a new sugarcane cultivar CP 10-1716. This cultivar is recommended for the Florida sugarcane growers with sand soils. The cross from which CP 10-1716 was selected (CP 00-2180 x Mix07Q; the specific male parent is unknown because of a polycross was made on 8 January 2008 at the USDA-ARS Sugarcane Field Station in Canal Point, FL. Data from 12 harvests of replicated yield trials that included CP 10-1716 were collected from October 2015 through December 2017. These trials were planted on sand soils at four locations; and were harvested in the plant-cane, first-ratoon, and second-ratoon crops at each location. The data from each of these crops were averaged to create a mean over all three crops. Major attributes of CP 10-1716 on these soils include its high tonnage of cane in the plant cane crop and its excellent disease package. This material will be available for research purposes, including development of new cultivars. It is requested that appropriate recognition be made if this germplasm contributes to the development of new breeding lines or cultivars, or other scientific advances.

Technical Abstract: ‘CP 10-1716’ (Reg. no. CV-195; PI 691536) sugarcane (a complex hybrid of Saccharum spp.) was developed and released (07 June 2018) through cooperative research conducted by the USDA-ARS Sugarcane Field Station at Canal Point, the University of Florida, and the Florida Sugar Cane League, Inc. for use on mineral (sand) soils. The cultivar is a result of cross X07-1257 (CP 00-2180 x Mix07Q; polycross male parent is unknown). Results of replicated trials on sand soils (four locations) averaged over 12 harvests from the three crops (i.e. plant cane, first ratoon, and second ratoon) showed that CP 10-1716 possesses the following agronomic traits: cane yield, sugar yield, and profitability (economic index, $/ha) that were similar to check cultivars (‘CL 88-4730’ and ‘CP 96-1252’) with strong disease resistances in CP 10-1716. Commercially recoverable sucrose (CRS) in CP 10-1716 was significantly lower than the check averages but the early CRS was not significantly different from the mean of the checks. The economic index for CP 10-1716 vs. the mean of the checks was $2490 ha-1 vs. $2445 ha-1, respectively, with CP 10-1716 showing no significant difference from the mean of the checks. CP 10-1716 was rated as moderately resistant to RSD and resistant to brown and orange rust, mosaic, smut, leaf scald, and yellow leaf disease on sand soils. CP 10-1716 is positive for the Bru1 molecular marker that is one of the indicators for brown rust resistance. CP 10-1716 has low to moderate freeze tolerances as it relates to sucrose degradation.
