Narrative
L 14-267 was released because of its high yield potential and broad-spectrum disease resistance. The final testing stage resulted in data from 62 trials at 12 representative sandy silt (light-textured) and clayey (heavy textured) soil locations. Cane yield of L 14-267 was comparable to that of ‘L 01-299’, the most widely grown cultivar in the Louisiana sugar industry, in the plant and first ratoon crops but significantly lower in the second ratoon crop. Sucrose content was significantly higher in L 14-267 than in L 01-299, in the plant and first ratoon crops and comparable to that of L 01-299 in the second ratoon crop. The performance of L 14-267 did not differ significantly between the two soil types for any of the traits. L 14-267 is a mid to late season maturing cultivar that appears to respond well to plant growth regulators but poorly to sub-freezing temperatures. L 14-267 displayed broad-spectrum disease resistant being resistant to mosaic, yellow leaf, smut, and ratoon stunt and moderately resistant to brown rust and leaf scald. L 14-267 is moderately susceptible to the sugarcane borer and the Mexican rice borer.

Pedigree
Description:
L 14-267 was derived from a cross, XL09-266 made in 2009 by scientists at the LSU AgCenter. The female parent HoCP 05-918, contains the lineages of two Saccharum spontaneous clones, SES 6 from India and US 56-15-8 from Thailand. The male parent, ‘L 01-283’, is a cultivar with declining acreage in the Louisiana sugar industry. The acreage is declining because the cultivar has a propensity to produce ‘off type’ phenotypes which have negatively affected its yield potential. L 01-283 also has S. spontaneous lineage (US 56-15-8 from Thailand) in its background. Saccharum spontaneum is the wild relative of the previously cultivated, sugar producing species, S. officinarum. Cultivated sugarcane are inter-specific hybrids derived by crossing (and backcrossing to S. officinarum) between these two species. For several decades, new cultivars were bred by crossing and selecting among these inter-specific hybrids. Recent breeding efforts in Louisiana have focused on a new round of introgression by crossing among cultivars and S. spontaneum. The new cultivar, L 14-267, is the combination of this effort.
