'CPCL 02-0926' (Reg. No. CV-150, PI 664936) 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 the 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 that was widely grown in Florida until it became susceptible to orange rust (caused by Puccinia kuehnii E.J. Butler) of sugarcane in 2007. 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 H. & P. Sydow), orange rust (caused by P. 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 its DNA. CPCL 02-0926 is the first sugarcane cultivar in which the status of a trait-linked marker was provided for release. 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. (Résumé d'auteur)
