Registration of ‘L 99‐226’ Sugarcane

Abstract

‘L 99‐226’ (Reg. No. CV‐138, PI 655533) sugarcane (a complex hybrid of Saccharum officinarum L., S. barberi Jeswiet, S. spontaneum L., and S. sinense Roxb. amend. Jeswiet) was released on 25 Apr. 2006 by the Louisiana State University Agricultural Center (LSU AgCenter) in cooperation with the USDA–ARS and the American Sugar Cane League, Inc. L 99‐226 was released because of its high sugar and cane yields along with excellent sucrose content. Data from 93 outfield trials indicate that L 99‐226 produced approximately 33% greater sugar yield and 9% greater sucrose content than ‘LCP 85‐384’ when averaged across all crops. The new cultivar is moderately resistant to brown rust disease (Puccinia melanocephala H. and P. Sydow), mosaic diseases, and the sugarcane borer (Diatraea saccharalis F.) and moderately susceptible to smut (Ustilago scitaminea Sydow & P. Sydow) and leaf scald [Xanthomonas albilineans (Ashby) Dowson]. The cross for L 99‐226 (XL94‐128) was made in fall 1994. Early stage clonal selection was done as single stools in 1996 followed by first clonal line trial selection in 1997 and second clonal line trial stage selection in 1998. Testing in replicated yield trials was conducted throughout the sugarcane growing area in south Louisiana from 2000 through 2005. Plant patent no. 18,807 was issued for L 99‐226 on 13 May 2008.
