Interpretive Summary: Sugarcane is an important crop in south Florida. Sugarcane in this region contributes >20% of U.S. domestic sugar production. New sugarcane cultivars are needed that yield well on organic (muck) soils and/or sand soils and have acceptable resistance to major diseases because 74% of sugarcane grows on muck and 26% of sugarcane grows on sand soils in Florida. 'CP 10-1208' was a new released sugarcane cultivar in 2017 for the Florida sand soils.Field data from three crops (plant cane and first- and second-ratoon crops) at three sand locations suggest CP 10-1208 yielded well in commercial sugarcane fields. Compared with CP 96-1252, CP 10-1208 had comparable sucrose yield and economic index. CP 10-1208 had 32.8% higher sucrose yield and 43.2% greater economic index than CL 88-4730. CP 10-1208 has acceptable levels of resistance to brown rust, leaf scald, sugarcane mosaic virus, and smut. It is expected that CP 10-1208 probably helps to improve sugarcane production on sand soils in Florida.

Technical Abstract: ‘CP 10-1208’ (Reg. No. CV-183, PI 688293) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. and released to growers for use on mineral (sand) soils in Florida in June 2017. It was selected from a bi-parental cross made at Canal Point (CP) on 21 Dec. 2007 with the CP sugarcane breeding lines CP 01-2390 (female parent) and TCP 98-4454 (male parent). CP 10-1208 was released by the Florida sugarcane variety committee because of its high cane and sucrose yields and acceptable commercial recoverable sucrose on sand soils, and its acceptable levels of resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E (mosaic), and smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.], but CP 10-1208 was moderately susceptible to orange rust (caused by Puccinia kuehnii E.J. Butler). Based on results of nine harvests with three crops (plant cane, first ratoon, and second ratoon) at three locations in final-stage replicated yield trials on sand soils and compared with two reference cultivars (CP 96-1252 and CL 88-4730), CP 10-1208 had 27.9 and 32.6% higher cane and sucrose yields than CL 88-4730, but did not differ from CP 96-1252 in either cane yield or sucrose yield. CP 10-1208 ranked 12th (plant cane) to 8th (first ratoon) for freeze tolerance among 23 genotypes tested.
