Registration of ‘CP 10‐1208’ Sugarcane

Abstract

‘CP 10‐1208’ (Reg. No. CV‐183, PI 688293) 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 released to growers for commercial use on mineral (sand) soils in Florida in June 2017. It was selected from a biparental cross made at Canal Point (CP) on 21 Dec. 2007 with the CP sugarcane breeding lines CP 01‐2390 (female parent) and TCP 98‐4454 (male parent). CP 10‐1208 was released by the Florida sugarcane variety committee because of its high cane and sucrose yields and acceptable commercial recoverable sucrose on sand soils, as well as its acceptable levels of resistance to brown rust, leaf scald, Sugarcane mosaic virus strain E (mosaic), and smut. Based on results of nine harvests with three crops (plant cane, first ratoon, and second ratoon) at three locations in final‐stage replicated yield trials on sand soils and compared with two reference cultivars (‘CP 96‐1252’ and ‘CL 88‐4730’), CP 10‐1208 had 27.9 and 32.6% higher cane and sucrose yields than CL 88‐4730 but did not differ from CP 96‐1252 in either cane yield or sucrose yield. Fiber concentration of CP 10‐1208 was 108.7 g kg−1 of cane. CP 10‐1208 ranked 12th (plant cane) to 8th (first ratoon) for freeze tolerance among 23 genotypes tested.
