Research to develop ‘CPCL 02-1295’ (Reg. No. CV-151, PI 664937) sugarcane (a complex hybrid of Saccharum spp.) was 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 02-1295 was released to growers in Florida on 20 Sept. 2011. CPCL 02-1295 was selected from a cross of ‘CP 88-1762’ × genotype CL 91-1637 made at Clewiston, FL on 26 Dec. 2001. The female parent, CP 88-1762, is a major commercial cultivar in Florida with high sucrose yields on both muck and sand soils, and it occupied 23.1% of the total Florida acreage in 2009. The male parent, CL 91-1637, reached the final testing stage of the USSC breeding program due to high biomass yields but was never released commercially because of its low sucrose content. CPCL 02-1295 is resistant to brown rust (caused by Puccinia melanocephala H. & P. Sydow), Sugarcane mosaic virus strain E (mosaic), ratoon stunt disease (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.), and smut (caused by Ustilago scitaminea H. & P. Sydow). CPCL 02-1295 is moderately susceptible to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson) and orange rust (caused by Puccinia kuehnii E.J. Butler). CPCL 02-1295 is recommended for both organic (muck) and sand soils in Florida, where it had high plant-cane tonnage and sucrose yields in our tests.
