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.

Registration of ‘HoCP 04‐838’ Sugarcane

“…HoCP 04‐838 is a high‐population cane, and through the second ratoon it was approximately 10% higher in stalks per hectare than all cultivars except ‘L 99‐233’ (Gravois et al, 2009) and ‘L 01‐283’ (Gravois et al, 2010). Finally, the stalk weight of HoCP 04‐838 is comparable to the other standards, except ‘L 99‐226’ (Bischoff et al, 2009). The cultivar L 99‐226 expressed the largest stalks of all the cultivars listed in Table 3, averaging 1.1 kg, a weight 23% greater than the average stalk weight for HoCP 04‐838.…”

Sugarcane Internode Composition During Crop Development

“…That study utilized 35 cultivars grown in single-row plots, 4.9 m long and 1.8 m apart replicated four times, arranged in randomized complete blocks. For this experiment, samples from five recent cultivars were used: HoCP 00-950 [31], HoCP 96-540 [32], L 97-128 [13], L 99-226 [4], and HoCP 01-534. Four of these, HoCP 00-950, HoCP 96-540, L 97-128, and L 99-226 are in current production in Louisiana [14].…”

Registration of ‘HoCP 09‐804’ Sugarcane

“…In the plant‐cane through second‐ratoon crops, HoCP 09‐804 was not significantly different than ‘L 01‐299’ (Gravois et al, 2011), the current leading cultivar in all traits (Table 2). Although the fiber content of HoCP 09‐804 was numerically higher than the other commercial cultivars, it was only significantly higher than ‘L 03‐371’ (Gravois et al, 2012) in all crops and ‘L 99‐226’ (Bischoff et al, 2009) in plant cane, ‘HoCP 96‐540’ (Tew et al, 2005) in the first ratoon, and all cultivars except ‘HoCP 04‐838’ (Todd et al, 2018) in the third ratoon.…”
