‘CPCL 02-0926’ 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 02-0926 was released to growers in Florida on 20 Sept. 2011. CPCL 02-0926 was selected from a cross between commercial cultivar CP 80-1743 and the USSC proprietary genotype CL 92-0046 made at Clewiston, FL on 20 Dec. 2001. CP 80-1743 is a high yielding, early maturing cultivar which was widely grown in Florida until the introduction of orange rust (caused by Puccinia kuehnii E.J. Butler) of sugarcane in 2007; CP 80-1743 is highly susceptible to orange rust and as a result it has been substantially reduced in acreage in Florida. The male parent of CPCL 02-0926, CL 92-0046, was advanced through the final stage of testing in the USSC cultivar program but not released for commercial production. CPCL 02-0926 has acceptable resistance to smut (caused by Ustilago scitaminea (Sydow & P. Sydow), orange rust and brown rust (caused by Puccinia melanocephala H. & P. Sydow). However, Bru1, a major gene for resistance to brown rust, was not detected in its DNA. CPCL 02-0926 is moderately resistant to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and Sugarcane mosaic virus strain E (mosaic). CPCL 02-0926 is expected to be used on both muck and sand soils in Florida.
