Interpretive Summary: The U.S. Department of Agriculture, Agricultural Research Service (ARS), Washington, D.C.; the University of Florida, Institute of Food and Agricultural Sciences (IFAS), 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 cultivar, CP 10-1619. CP 10-1619 is recommended for Florida sugarcane growers with sand soils. Major attributes of CP 10-1619 on these soils include its high tonnage of cane biomass and its quantity of sugar, especially as plant cane.

Technical Abstract: ‘CP 10-1619’ (Reg. No. ; PI 687220) sugarcane (a complex hybrid of Saccharum spp.) was developed and released (5 June 2017) 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 clone results from CP cross # X08-1197A (CP 97-1777 x Poly 08-19), and possessed the following agronomic traits: high cane and sucrose yields, particularly as plant cane, as well as its high economic index on sand soils. Results of replicated trials on sand soils (2015 – 2017; three locations) were averaged over 9 harvests from the three crops (i.e. plant cane, first ratoon, and second ratoon). Yield comparisons with check cultivars (‘CL 88-4730’ and ‘CP 96-1252’) indicated CP 10-1619 had significantly higher means than CL 88-4730 < (P = 0.10) for the following: cane yield (131.6 Mg ha-1); sugar yield (16.5 Mg ha-1); and economic index (3,037 $ ha-1). CP 10-1619 had significantly (P = 0.10) higher means than both check cultivars for stalk weight (0.9 kg stalk-1) and stalk count (134,350 stalks ha-1). CP 10-1619 has demonstrated moderate resistance to both brown and orange rusts, as well as smut. The clone is resistant to mosaic and leaf scald on sand soils; and is moderately susceptible to ratoon stunting disease. CP 10-1619 is moderately resistant to freezing temperatures.
