Registration of ‘L 14‐267’ sugarcane

Abstract

Abstract‘L 14‐267’ (Reg. no. CV‐213, PI 701487) sugarcane (Saccharum spp. hybrid) was released for commercial production in Louisiana 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 was comparable to that of L 01‐299 in the second ratoon crop. Sugar yield was significantly higher in L 14‐267 than in L 01‐299 in the plant crop, comparable in the first ratoon crop but significantly lower 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 resistance, 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.
