Abstract ‘CP 13‐4513’ (Reg. no. CV‐221, PI 705649) sugarcane, developed through cooperative research conducted by the USDA‐ARS, the University of Florida, and the Florida Sugar Cane League, Inc., was released to growers for mineral soils in Florida in June 2021. The expansion potential of sugarcane acreage on mineral soils in Florida increases the importance of new cultivar development for this soil type. CP 13‐4513 offers a good disease package with its resistance to leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), orange rust (caused by Puccinia kuehnii E.J. Butler), ratoon stunt disease (caused by Leifsonia xyli subsp. xyli Evtushenko et al.), Sugarcane mosaic virus (strain E), and moderate resistance to smut caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.. CP 13‐4513 is susceptible to brown rust (caused by Puccinia melanocephala H. & P. Sydow), but this disease can be efficiently controlled with fungicides. The 3‐year sandy‐soil production summary (i.e., plant cane, first ratoon, and second ratoon) demonstrated commercially recoverable sucrose (CRS), cane yields, and sugar yields comparable to the commercial sand check ‘CL 88‐4730’. Compared to the other reference check, ‘CP 96‐1252’, CP 13‐4513 produced more CRS and less cane yield. The economic index of CP 13‐4513 was not significantly different from that of CL 88‐4730 or CP 96‐1252. CP 13‐4513 displayed excellent germination on sand, and greater cane height, tillering capability, and canopy shading than ‘CL 88‐4730’ in plant cane. CP 13‐4513 exhibits heavy flowering that starts in early December.
