Registration of 'CP 88-1165' Sugarcane
2008
'CP 88-1165' (Reg. No. CV-131, PI 651884) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA-ARS, the Centro Guatemalteco de Investigacion y Capacitacion de la Cana de Azucar, and the University of Florida. It was released to growers in Guatemala in September 2004. CP 88-1165 was selected from the cross 'CL 61-620' x CP 81-1302 made at Canal Point, FL, in January 1986. The female parent, CL 61-620, formerly a major commercial cultivar in Florida, was developed by a private breeding program in Clewiston, FL, conducted by the United States Sugar Corp. The male parent, CP 81-1302, was advanced to the final testing stage (Stage 4) of the Canal Point (CP) cultivar development program but was not released due to susceptibility to brown rust (caused by Puccinia melanocephala Syd. & P. Syd.). CP 88-1165 was not released in Florida because of its susceptibility to brown rust and low yield of commercial recoverable sucrose. However, after testing in Guatemala, CP 88-1165 was released there because of its high plant cane and ratoon per hectare yields of cane and sucrose and its acceptable resistance or tolerance to smut [caused by Ustilago scitaminea (Sydow & P. Sydow], brown rust, Sugarcane mosaic virus strain E (mosaic), Sugarcane yellow leaf virus, and red stripe (Acidovorax avenae subsp. avenae) in Guatemala.
