Registration of ‘Ho 02-113’ Sugarcane. Journal of Plant Registrations. 7(1):51-57. DOI:10.3198/jpr2011.11.0605crc. Interpretive Summary: The high-fiber sugarcane (energycane) variety Ho 02-113 was released by the USDA-ARS Sugarcane Research Unit in Houma, Louisiana for use as a feedstock for biofuel production. Varietal options were limited to three varieties, and the leading energycane variety in the U.S., L 79-1002, is susceptible to smut disease, which limits the number of crops that can be harvested from a single planting. Ho 02-113 yielded, on average, 20.2 tons of dry matter per acre as compared to the yield of L 79-1002 at 16.7 tons per acre. It was also included in inoculated disease screening tests for smut, and leaf scald, and rated for infection by brown rust and mosaic under high levels of natural inoculums. Despite multiple evaluations, no disease has been observed in this variety, making it a superior alternative to L 79-1002. The release of Ho 02-113 gives the emerging biofuel industry another feedstock option. The lack of disease to-date in this variety lessens the potential impact on the existing sugarcane industry by reducing the amount of inoculum for both crops.
Technical Abstract: ‘Ho 02-113’ sugarcane was released by the USDA-ARS Sugarcane Research Unit working cooperatively with the Louisiana State University Agricultural Center, and the American Sugarcane League of the U.S.A. This high-fiber sugarcane variety was released for use as a biofuel feedstock to fill the rising industry demand. ‘Ho 02-113’ is a progeny of the cross ‘SES 234’ x ‘LCP 85-384’ made in Houma, Louisiana in 2001. The variety was selected at the USDA in Houma, LA, evaluated in multiple locations, and harvested from six locations in six plant-cane, two first-ratoon, two second-ratoon, and two-third ratoon replicated tests. ‘Ho 02-113’ averaged 125.3, 12.8, 32.8, and 43.5 tons of cane, soluble solids, fiber, and total dry weight per hectare, respectively. These were significantly higher than the leading high-fiber sugarcane variety ‘L79-1002’, which averaged 102.7, 9.6, 27.8, and 37.4 tons of cane, soluble solids, fiber, and total dry weight per hectare, respectively. The variety is resistant to leaf scald [caused by Xanthomonas albilinenas (Ashby) Dawson] and smut (caused by Ustilago scitaminea H. and P. Syndow) in inoculated tests and showed no symptoms of brown rust nor mosaic (caused by either Sugarcane mosaic virus or sorghum mosaic virus) when exposed to high levels of natural inoculums.
