Registration Of 'Ho 11-573' Sugarcane

'Ho 11-573' (Reg. no. CV-201, PI 698597) sugarcane (an interspecific hybrid of Saccharum officinarum L., S. barberi Jeswiet, S. spontaneum L., and S. sinense Roxb. amend. Jeswiet) was selected and evaluated by scientists at the USDA-ARS, working cooperatively with the Louisiana State University Agricultural Center, the American Sugar Cane League of the U.S.A., Inc., and Rio Farms, Inc. It was released primarily for the Texas sugarcane industry. In field evaluations combined across crops and in ratoons, Ho 11-573 had yields equivalent to CP 89-2143 and CP 72-1210, the most widely grown Texas commercial cultivars. Cane yield (Mg/ha) of Ho 11-573 from plant-cane crop evaluations at five locations was significantly higher than CP 89-2143 or CP 72-1210. Ho 11-573 is moderately susceptible to smut and brown rust. It is resistant to leaf scald but is susceptible to ratoon stunt. Sugarcane mosaic and orange rust have not been observed on Ho 11-573.
