Interpretive Summary: This is the formal publication of the release of the sugarcane variety Ho 07-613. The variety was originally created from a cross made at the USDA-ARS Sugarcane Research Unit in Houma, LA. It was evaluated by members of the USDA team alongside cooperators from the Louisiana State University Agricultural Center and the American Sugar Cane League of the U.S.A., Inc over a 13 year period. It was officially released in 2014 to the Louisiana sugarcane industry. The variety was tested through the entire crop cycle (plant-cane through second ratoon crops) at 12 farm locations which were on commercial sugarcane fields, and was compared to the most widely grown variety in Louisiana at the time (HoCP 96-540). Ho 07-613 has high sucrose yields and is resistant to the diseases smut, and sorghum mosaic virus, and moderately resistant to brown rust and leaf scald diseases. It is tolerant to ratoon stunt disease, and moderately resistant to sugarcane borer (a major insect pest). When sprayed with low levels of glyphosate a few weeks prior to harvest, the variety has a moderate response of increased sucrose concentration. Ho 07-613 has a high yield potential, low fiber content, and good disease resistance making it a useful addition to existing commercial sugarcane varieties in Louisiana.

Technical Abstract: ‘Ho 07-613’ (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, Inc. It was released to growers in Louisiana in 2014. The variety was tested across the crop cycle (plant-cane first-, and second-ratoon) at 12 farm locations, and compared to HoCP 96-540, the most widely grown variety in Louisiana during that time. The plant-cane sucrose yield (Mg ha-1) of Ho 07-613 was equivalent to HoCP 96-540, and sucrose content was significantly higher. Ho 07-613 has moderately-early maturity and poor mature-stalk cold tolerance. The variety is resistant to smut (Sporisorium scitamineum), and Sorghum Mosaic Virus, tolerant of ratoon stunt (Leifsonia xyli) and moderately resistant to brown rust (Puccinia melanocephala) and leaf scald caused by Xanthomonas albilineans. It is moderately resistant to sugarcane borer, Diatraea saccharalis F and moderately responsive to glyphosate ripener. Ho 07-613’s high yield potential, low fiber and disease resistance make it a useful addition to existing commercial sugarcane varieties in Louisiana.
