“…The introgression breeding effort initiated in the 1950s is ongoing (Hale et al., 2021) and continues to be of great benefit to the Louisiana commercial breeding and selection programs. Indeed, the female parent of L 14‐267, HoCP 05‐918, is a BC 4 descendant of yet another S. spontaneum clone, SES 6 from India (Figure 1).…”

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. INTRODUCTIONSugarcane (Saccharum spp. hybrid) is a tall perennial grass of tropical origin that is cultivated for its ability to store sucrose in its stalks. Cultivated in more than 100 countries (FAOSTAT, 2020), sugarcane is a crop of great economic significance in many regions of the world and accounts Abbreviations: ASCL, American Sugar Cane League of the U.S.A.

“…Breeding innovation has supported the expansion of sugarcane production toward the Northern border of Louisiana, which increased the likelihood of freeze damage in late fall and winter. 1 Cold tolerance is highly cultivar-dependent, and injuries as severe as stalk cracking are observed after several hours of subfreezing temperatures, followed by juice deterioration. 2 Although management practices including ripener 3 have been implemented for early harvesting, damaging freeze as recent as 2022 in Louisiana impacted factory operations by decreasing the quality of incoming sugarcane.…”

“…Sugarcane (Saccharum spp.) is a highly productive C 4 grass crop, yielding an average of more than 75 metric tons ha −1 y −1 in the nine-month growing season of wet, temperate south Louisiana [1]. The need for adequate drainage in Louisiana's wet climate and the accommodation of the wheel spacing of tractors and other machinery led to a specific row configuration of 1.8 m wide and 0.25-0.3 m tall rows [2].…”

“…Theoretically, increasing any one of these variables can increase yield, and using all water available for transpiration is the most effective use of available water [16,17]. In the case of sugarcane, the HI is closely related to aboveground biomass and is a major focus of the sugarcane breeding program [1,18,19]. In contrast, no direct efforts have been made to increase WUE or sugarcane water use, which, too, can increase yields with respect to water resources, even though sugarcane is grown in a water-abundant agroecosystem that should be able to support an increase in water uptake.…”

Row Spacing and the Use of Plant-Available Water in Sugarcane Cultivation in Water-Abundant Louisiana

Optimizing row spacing can potentially improve yields when resources such as light and water are limited. Sugarcane in Louisiana is principally grown on rows spaced 1.8 m apart, but interest in planting on 2.4 m rows is increasing. In this study, we hypothesized that wider row spacing would have greater water availability. Soil moisture sensors were placed at 15, 30, and 45 cm depths in treatments: 1.8 and 2.4 m row spacings, two varieties (L 01-299 and HoCP 04-838), and two planting dates. Soil moisture was monitored in 15-min intervals from 2017 to 2020. Mean volumetric water content was slightly greater in 2.4 m than 1.8 m row spacing at 15 and 45 cm, but the biggest difference was observed when soil water content reached its lowest levels where 2.4 m rows had 1.1, 3.1, and 9.8 times more water available at 15, 30, and 45 cm, respectively, compared to 1.8 m row spacing. However, in both row spacings, plant-available water was always present in the top 45 cm, even during periods of low rainfall. Potentially, high water availability provides an opportunity to increase photosynthesis in sugarcane varieties by selecting for greater photosynthetic capacity and CO2 uptake through increasesd stomatal conductance.
