‘CPCL 05-1102’ (Reg. No. CV-157, PI 667556) 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 adapted to muck soils, where it was used only briefly in commercial plantings of USSC due to yield losses to ratoon stunt (caused by Leifsonia xyli subsp. xyli). 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.
