Interpretive Summary: A new sugarcane variety, 'CP 09-2392', was developed through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and was released to growers in June 2016. 'CP09-2392' was superior to the reference variety 'CL 88-4730' on sand soils in Florida with respect to stalk weight, cane yield, sucrose content, sucrose yield, and overall profitability. The variety is resistant to several diseases, including brown rust, leaf scald, ratoon stunt, smut, Sugarcane mosaic virus, and Sugarcane yellow leaf virus. It is also moderately resistant to orange rust, and has good freeze tolerance. 'CP 09-2392' is recommended for sand soils in Florida.
Technical Abstract: CP 09-2392’ (Reg. No. CV-182; PI 688299) 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 to growers in June 2016. ‘CP 09-2392’ was selected from a cross made at the USDA-ARS Sugarcane Field Station in Canal Point, Florida, in December 2007. The female parent was CP 01-2390; the identity of the male parent is difficult to determine as the cross included multiple potential male parents, i.e. a polycross. ‘CP 09-2392’ was superior to the reference variety ‘CL 88-4730’ on sand soils with regards to stalk weight, cane yield, commercial recoverable sucrose (a measure of sucrose content), sucrose yield, and economic index (i.e. overall profitability). The variety is resistant to brown rust (Puccinia melanocephala H. & P. Sydow), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), ratoon stunt (caused by Leifsonia xyli subsp. xyli Davis), Sugarcane mosaic virus strain E (mosaic), smut (Sporisorium scitamineum (Syd.) Piepenbring et al.), and Sugarcane yellow leaf virus, and is moderately resistant to orange rust (Puccinia kuehnii E.J. Butler). In addition, ‘CP 09-2392’ has good freeze tolerance. This variety is recommended for mineral (sand) soils in Florida.
