CP 04-1566’ 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 was released to growers in Florida on 30 Sept. 2011. CP 04-1566 was selected from the cross X01-0246 (cultivars CP 89-2377 X CP 96-1252) made at Canal Point, FL on 29 Nov. 2001. Both parents were released for commercial production: CP 89-2377 for organic (muck) soils only and CP 96-1252 for both muck and sand soils. CP 04-1566 was tested in Stage 4 only on sand soils in Florida because of its superior yields on sand soils and substandard yields on organic soils in Stage 3. CP 04-1566 was released for sand soils because of its moderate resistant to all the major diseases in Florida: brown rust (caused by Puccinia melanocephala H. & P. Sydow) even though it does not contain the gene for brown rust resistance (Bru1), orange rust (caused by Puccinia kuehnii E.J. Butler), Sugarcane mosaic virus strain E (mosaic) smut (caused by Ustilago scitaminea H. & P. Sydow), and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.) and is resistant to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), in Florida. CP 04-1566 has a cane yield and commercial recoverable sucrose (CRS)equal to those of the commercial check, CP 78-1628. CP 04-1566 is susceptible to Sugar Cane Yellow Leaf Virus and had moderate to poor tolerance to freezes based on its rank in CRS in 2010-11 and 2011-12 at the University of Florida Hague Farm near Gainesville, Florida.
