Registration of ‘CP 08‐1110’ Sugarcane

Abstract

‘CP 08‐1110’ (Reg. No. CV‐171, PI 678579) 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 and was released to growers for use on mineral (sand) soils in Florida in June 2015. CP 08‐1110 was selected from a biparental cross made at Canal Point, FL, on 20 Dec. 2006 with the Canal Point sugarcane breeding lines CP 01‐2459 (female parent) and CP 00‐2188 (male parent). CP 08‐1110 was released by the Florida sugarcane variety committee because of its high cane and sucrose yields and acceptable commercial recoverable sucrose on sand soils, and because of its acceptable levels of resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), orange rust (caused by Puccinia kuehnii E.J. Butler), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E, ratoon stunt (caused by Leifsonia xyli subsp. xyli Evtsuhenko et al.), and smut [caused by Sporisorium scitamineum (Syd.) M. Piepenbring et al.]. Given the 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 89‐2143 and CL 88‐4730), CP 08‐1110 had 24.9 and 30.4% higher cane yield and 18.5 and 29.0% higher sucrose yield, respectively (P < 0.05). CP 08‐1110 ranked 16th (plant cane) to 19th (first ratoon) for freeze tolerance among 22 genotypes in field tests for temporal sucrose deterioration.
