Technical Abstract: Recently-released L 99-226, HoCP 00-950, and L 01-283 all mature significantly earlier and maintain a higher overall sucrose content than previously released varieties in Louisiana. The advantage that high-sucrose varieties have over those with moderate sucrose content is that less cane must be harvested, transported, and processed to obtain the same amount of sugar per acre. Considering the ever-increasing harvesting, hauling, and grinding costs per ton of cane handled, the economic advantage of harvesting and processing high sucrose varieties can be substantial. Data from yield tests and maturity studies suggest that these newer varieties should contribute to higher profits for growers and millers. However, growers should be aware that practices such as repeated early-season harvesting of high-sucrose varieties, and unnecessary use of chemical ripeners may cause them to underperform. It will benefit the sugar industry in Louisiana to better understand and appropriately manage high sucrose varieties currently available in order to maximize their longevity in the industry and potentially increase profitability while maintaining genetic diversity.
