Interpretive Summary: In order to promote sustainable crop development and sugarcane output in US agriculture, cultivars must be continuously improved. A new cultivar, CP 12-2035, was released by the USDA-ARS, the University of Florida, and the Florida Sugarcane League Inc. because of its heavier stalks, higher sugar yields and comparable economic success on Florida sand soils. It also has good disease resistance package. In late-stage yield trials, CP 12-2035 sugar yields were 23.4, 31.4, and 42.9 % higher than that of the check varieties CP 03-1912, CP 96-1252, and CPCL 97-2730, respectively. CP 12-2035 also produced heavier stalks than all three tested reference checks. With its demonstrated resistance to disease, and elevated sugar production capacity, CP 12-2035 is expected to positively influence both sugarcane production and crop sustainability in Florida.

Technical Abstract: ‘CP 12-2035’ (Reg. No. ; PI 700305) sugarcane cultivar (a complex hybrid of Saccharum spp.) was released to growers in July 2024 for cultivating on sand soils in Florida after a decade-long advancement through cooperative research conducted by the USDA-ARS, the Florida Sugar Cane League Inc., and the University of Florida. It originated from a poly-cross at Canal Point (CP). The Florida Sugarcane Variety Committee recommended release of CP 12-2035 due to its high sugar yields, sucrose content on sand soils, and acceptable disease resistance. CP 12-2035 has demonstrated resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), and moderate resistance to mosaic (caused by Sugarcane mosaic virus strain E), and ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtushenko et al.), and smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbr. et al.], and moderate susceptibility to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson). In late-stage yield trials, CP 12-2035 sugar yields were 23.4, 31.4, and 42.9 % higher than that of the check varieties ‘CP 03-1912’, ‘CP 96-1252’, and ‘CPCL 97-2730’, respectively. CP 12-2035 also produced heavier stalks than all three tested reference checks. It was more tolerant to cold stress over reference checks. With its demonstrated resistance to disease, and elevated sugar production capacity, CP 12-2035 is expected to positively influence both sugarcane production and crop sustainability in Florida.
