‘CP 04‐1935’ (Reg. No. CV‐154, PI 667660) 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 and was released to growers in Florida on 20 Sept. 2011. CP 04‐1935 was selected from the cross CP 94‐2059/CP 84‐1322 made at Canal Point, FL on 8 Dec. 1998. In the final stage of selection, CP 04‐1935 was tested for yield performance at two sand‐soil locations along with 15 other genotypes across three crop years and for freeze tolerance in northern Florida for two crop years. CP 04‐1935 produced an 11% higher cane yield, a 3.5% higher sucrose content, and a 14.5% higher sucrose yield than the reference sand cultivar CP 78‐1628. CP 04‐1935 is resistant to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), mosaic (caused by Sugarcane mosaic virus strain E), to smut (caused by Ustilago scitaminea H. & P. Sydow), and to eyespot [caused by the Bipolaris sacchari (E.J. Butler) Shoemaker]; it is moderately resistant to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and to ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtushenko et al.), but it is susceptible to Sugarcane yellow leaf virus . CP 04‐1935 performed significantly worse under freeze conditions than CP 89‐2143, the Florida industry standard for acceptable freeze tolerance. With its profitability predicted to be 19% higher than that of CP 78‐1628, combined with a good disease profile, CP 04‐1935 was recommended for planting on sand soils in Florida.
