Registration of ‘HoCP 11-537’ sugarcane. Journal of Plant Registrations. 13:187-192. https://doi.org/10.3198/jpr2018.10.0066crc.
Interpretive Summary: New sugarcane varieties are necessary to continue to have high sugar yields in Texas. To fill this need scientists from Rio Grande sugar producing portion of Texas have been evaluating advanced germplasm from Louisiana under Texas conditions to identify new cultivars for Texas. The clone HoCP 11-537 was dropped from the USDA Louisiana program because of low sugar yield but was released to growers in Texas because of it high yields in Texas. This variety had equivalent yields to existing varities by introduced much needed cultivar diversity to the Texas industry preventing crop failure if the current cultivars decline.
Technical Abstract: ‘HoCP 11-537’ (Reg. No. CV-186, PI 688683) 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 industry, in March 2018. In field evaluations, HoCP 11-537 had yields comparable to CP 89-2143 and CP 72-1210, the most widely grown Texas commercial cultivars. Sugar yield (Mg/hectare), sucrose content (kg sucrose/Mg of cane), and cane yield (Mg/hectare) of HoCP 11-537 in five plant-cane, first-ratoon, and second-ratoon crop evaluations did not differ from those of CP 89-2143 or CP 72-1210. HoCP 11-537 is moderately susceptible to smut (Sporisorium scitamineum) and leaf scald (Xanthomonas albilineans), and is susceptible to brown rust (Puccinia melanocephala) and ratoon stunt (Leifsonia xyli). Sugarcane mosaic caused by Sorghum mosaic virus and orange rust caused by P. kuehnii have not been observed on HoCP 11-537.
