‘CPCL 05-1102’ sugarcane (a complex hybrid of Saccharum spp.) is the product of research initiated by the United States Sugar Corporation (USSC), and completed cooperatively by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CPCL 05-1102 was released to growers in Florida on 16 Oct. 2012. CPCL 05-1102 was selected from a cross between the USSC proprietary cultivars CL 89-5189 (female) and CL 88-4730 (male) made at Clewiston, FL on 18 Dec. 2000. CL 89-5189 was used briefly in commercial plantings of USSC because it quickly became susceptible to ratoon stunt (caused by Leifsonia xyli subsp. xyli), and CL 88-4730 is widely used on commercial plantings of USSC, particularly on sand soils. CPCL 05-1102 has acceptable resistance to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E (mosaic), smut (caused by Ustilago scitaminea (Sydow & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), and brown rust (caused by Puccinia melanocephala H. & P. Sydow). Bru1, a major gene for resistance to brown rust, was not detected in the DNA of CPCL 05-1102. CPCL 05-1102 has high cane and sucrose yields and excellent freeze tolerance and is expected to be used on muck soils in Florida.
