Registration of ‘CPCL 02‐1295’ Sugarcane

Abstract

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.
