Interpretive Summary: ‘CP 07-2320’ is a new variety of sugarcane 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 September 2015. ‘CP 07-2320’ was selected from a cross made at the USDA-ARS Sugarcane Field Station in Canal Point, Florida, in December 2005. The female parent was CP 02-2065 and the male parent was CP 96-1865. ‘CP 07-2320’ was superior to the reference variety CP 89-2143 for muck soils with regards to stalk population, stalk weight, cane yield, sucrose content, sugar yield, and overall profitability. ‘CP 07-2320’ was superior to the reference variety CP 78-1628 for sand soils with respect to stalk weight, cane yield, sucrose content, sugar yield, and overall profitability. The variety is resistant to brown rust, leaf scald, and ratoon stunt. ‘CP 07-2320’ is susceptible to mosaic virus based on the results of an artificial inoculation test, and is moderately susceptible to smut, sugarcane yellow leaf virus, and orange rust under field conditions. This variety is recommended for both muck and sandy soils in Florida.

Technical Abstract: 'CP 07-2320' (registration number____; PI _____) 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 September 2015. ‘CP 07-2320’ was selected from a cross made at the USDA-ARS Sugarcane Field Station in Canal Point, Florida, in December 2005. The female parent was CP 02-2065 and the male parent was CP 96-1865. ‘CP 07-2320’ was superior to the reference variety CP 89-2143 for muck soils with regards to stalk population, stalk weight, cane yield, sucrose content, sugar yield, and overall profitability. ‘CP 07-2320’ was superior to the reference variety CP 78-1628 for sand soils with respect to stalk weight, cane yield, sucrose content, sugar yield, and overall profitability. The variety is resistant to brown rust (Puccinia melanocephala H. & P. Sydow), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), and ratoon stunt (caused by Clavibacter xyli subsp. xyli Davis). ‘CP 07-2320’ is susceptible to Sugarcane mosaic virus strain E (mosaic), based on the results of an artificial inoculation test, and is moderately susceptible to smut (Sporisorium scitamineum (Syd.) Piepenbring et al.), Sugarcane yellow leaf virus, and orange rust (Puccinia kuehnii E.J. Butler) under field conditions. This variety is recommended for both organic (muck) and mineral (sand) soils in Florida.
