Abstract

Abstract : 'CP 04‐1844' (Reg. No. CV‐153, PI 664935) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA‐ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and was released in Florida on 20 Sept. 2011. CP 04‐1844 was selected from the cross X01‐0336 (CP 97‐1989 × CP 84‐1198) made at Canal Point, FL on 5 Dec. 2001. The female parent, CP 97‐1989, was a high‐tonnage cultivar released for sand soils in Florida but was not grown extensively because it became susceptible to brown rust (caused by Puccinia melanocephala H. & P. Sydow) after its release. The male parent, CP 84‐1198, is a cultivar with moderate tonnage and sucrose levels that peaked at 5.1% of the commercial acreage in Florida and is still grown commercially. CP 04‐1844 was tested in the final selection stage (stage 4) on sand soils in Florida and was released because of its high cane and sucrose yields and acceptable commercial recoverable sucrose on these soils, as well as for its resistance to brown rust, orange rust (caused by Puccinia kuehnii E.J. Butler), and smut (caused by Ustilago scitaminea H. & P. Sydow) and its moderate resistance to Sugarcane mosaic virus strain E (mosaic) and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtushenko et al.) in Florida. CP 04‐1844 is susceptible to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson) and Sugarcane yellow leaf virus . The freeze tolerance of CP 04‐1844 was at least equal to that of cultivar CP 89‐2143 during 2 yr of testing. CP 89‐2143 is considered to have acceptable freeze tolerance for Florida.
