Interpretive Summary:

Technical Abstract: The clone Ho 07-613 will be up for release to Louisiana sugarcane farmers in May of 2014. This potential new variety is a joint release of the United States Department of Agriculture, the Louisiana State University Agricultural Center, and the American Sugar Cane League of the U.S.A., Inc. Ho 07-613 is a clone selected from a cross between HoCP 00-905 and HoCP 96-540 that was made in Houma, LA in 2002. It was selected as a single stool in 2004 and assigned a permanent variety designation in 2007. During 2011 through 2013, Ho 07-613 was evaluated in a total of thirty-three plant-cane, twenty-one first-ratoon, and ten second-ratoon outfield trials. In these evaluations, Ho 07-613 yielded tonnage comparable to the yields of HoCP96-540, the current major variety being grown by sugarcane farmers in Louisiana. However, Ho 07- 613 was comparatively a sweeter variety than HoCP 96-540 as its average sucrose content (g per kg of sugarcane) was 5% higher (146 vs 138 g/kg) than that of HoCP 96-540 for all three crops. The average stalk weight of Ho 07-613 was comparable to HoCP 96-540 (1.03 vs 1.02 kg). Ho 07-613 is a low fiber variety; its fiber percent cane is less than HoCP 96-540 (10.6% vs 11.6%). Though these two varieties were roughly equal in stalk population, Ho 07-613 was 5% higher in stalks per ha (70,302 vs 66,842). Additionally, Ho 07-613 is resistant to smut caused by Ustilago scitaminea, brown rust caused by Puccinia melanocephala, leaf scald caused by Xanthamonas albilineans, and ratoon stunt caused by Leifsonia xyli subsp. xyli. At low to moderate sugarcane borer (Diatraea saccharalis) infestations, the variety is moderately resistant to the borer; however, at higher borer infestations the variety is expected to be moderately susceptible like HoCP 96-540. A concern for this variety is its brittleness; a trait that can be problematic to sugarcane farmers if this variety lodges prior to planting or harvesting.
