Registration of ‘CPCL 05‐1791’ Sugarcane

Abstract

Development of ‘CPCL 05‐1791’ (Reg. No. CV‐156, PI 667555) sugarcane (a complex hybrid of Saccharum spp.) is the latest in a series of commercial sugarcane cultivar releases originating from the United States Sugar Corporation (USSC) and completed by the cooperative Canal Point sugarcane breeding and selection program (CP program) which includes the USDA‐ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CPCL 05‐1791, which was released in Florida on 20 Sept. 2012, was selected from a cross of CP 96‐1252 × CL 90‐4725 made at Clewiston, FL on 5 Dec. 2002. The male parent, CL 90‐4725, is a proprietary cultivar of USSC. CPCL 05‐1791 was released because of its high cane yield, moderate levels of commercial recoverable sucrose on mineral (sand) soils, and its resistance to smut (caused by Ustilago scitaminea H. & P. Sydow), Sugarcane mosaic virus strain E (mosaic), and orange rust (caused by Puccinia kuehnii E.J. Butler), and its moderate resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow) and leaf scald (caused by Xanthomonas albilineans Ashby, Dowson). All of these diseases are of economic importance to sugarcane production in Florida.
