Interpretive Summary: New sugarcane varieties are necessary for continued high yields in Louisiana because of adverse conditions such as early freezes, and disease and insect pests. The variety development program at the LSU AgCenter in St. Gabriel, Louisiana, makes crosses with favorable clones and evaluates their progeny throughout Louisiana. One of the varieties evaluated, the released variety 'L 11-183', has high yield in comparison to cultivar HoCP 96-540. It is also resistant to the diseases smut and leaf scald. The variety L 11-183 has the yield traits and disease resistance that will make it profitable for farmers in Louisiana.
Technical Abstract: ‘L 11-183’ sugarcane (interspecific hybrid of Saccharum spp.) was derived from a cross between HoCP 92-624 as the female and ‘LCP 85-384’ as the male parent. Early stage clonal selection by researchers at the Louisiana State University Agricultural Center led to the assignment of a permanent variety number in 2011. The variety was further evaluated cooperatively with scientists from the USDA-ARS and the American Sugar Cane League. L 11 183 was jointly released to the Louisiana sugar industry on May 11, 2018. L 11-183 was released because of its high yield potential compared with HoCP 96-540 and L 01-299, two of the most widely grown varieties in Louisiana at the time. In the final testing stage, data were collected from across 12 locations and three crops (plant cane, first and second ratoon) with multiple crop years within locations. Combined across all crops, cane yield was 5% greater in L 11-183 than HoCP 96-540 but 4% less compared with L 01-299. Sucrose yield in L 11-183 was comparable to that of L 01-299 but 3% greater than that of HoCP 96-540. The new cultivar is resistant to smut (Sporisorium scitamineum Syd. & P. Syd.), moderately resistant to leaf scald (Xanthomonas albilineans (Ashby) Dowson), sugarcane yellow leaf virus and ratoon stunting (Leifsonia xyli subsp. xyli), moderately susceptible to brown rust (Puccinia melanocephala (Syd. & P. Syd.)) and mosaic virus, and susceptible to the sugarcane borer (Diatraea saccharalis).
