Registration of ‘CP 09‐2392’ Sugarcane

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 Sugarcane 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, FL, 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 cultivar ‘CL 88‐4730’ on sand soils with regard to stalk weight, cane yield, commercial recoverable sucrose (a measure of sucrose content), sucrose yield, and economic index (i.e., overall profitability). CP 09‐2392 is resistant to brown rust, leaf scald, ratoon stunt, Sugarcane mosaic virus strain E (mosaic), smut, and Sugarcane yellow leaf virus and is moderately resistant to orange rust. In addition, CP 09‐2392 has good freeze tolerance. This cultivar is recommended for mineral (sand) soils in Florida.
