Interpretive Summary: New sugarcane varieties are necessary for south Texas to increase diversity and increase yield. To fill this need, elite clones from the variety development program at the USDA-ARS Sugarcane Research Station in Houma Louisiana are evaluated in Texas to identify new adapted cultivars to release for that region. One of these, Ho 11-573, was dropped from the Louisiana program for poor ratoon yield, but has superior plant cane yield to the Texas standards and is not significantly different in ratoon. The release of this cultivar gives the Texas industry a new high yielding cultivar that increases diversity to prevent crop failure if the current cultivars decline.

Technical Abstract: ‘Ho 11-573’ (Reg. No. CV-xxx, PI xxxxxx) sugarcane (an interspecific hybrid of S. officinarum, S. barberi Jeswiet, S. spontaneum, 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, and the American Sugar Cane League of the U.S.A., Inc. and Rio Farms Inc. It was released, primarily for the Texas sugar industry. In field evaluations, Ho 11-573 had yields comparable to CP 89-2143 and CP 72-1210, the most widely grown Texas commercial cultivars. Cane yield (Mg/hectare) 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 (Sporisorium scitamineum) and brown rust (Puccinia melanocephala). It is resistant to leaf scald (Xanthomonas albilineans), and is susceptible to ratoon stunt (Leifsonia xyli). Sugarcane mosaic caused by Sorghum mosaic virus and orange rust caused by P. kuehnii have not been observed on Ho 11-573.
