Interpretive Summary: Sugarcane is harvested during a 5 month period (October ' March) in the Everglades Agricultural area of South Florida Sugarcane cultivars vary in time and quantity of sucrose accumulative. The object of this paper is to provide sucrose accumulation curves and provide harvest schedule recommendations based on this information for commercial cultivars. These recommendations were based data collected at 2 week intervals over 4 consecutive harvest seasons. Cultivar recommended for harvest in the early season starting October 14 (0-50 days) CP 70-1133, CP 80-1743, CP 88-1762; mid-season (50-100 days) CP 78-1628, CP 84-1198; late-season (100-150 days) CP 72-1210, CP 72-2086, CP 80-1827, CP 85-1382, CP 88-1508, CP 89-2377. CP 89-2143 had the highest sucrose accumulation of all cultivars at all sampling periods and should be considered by growers wanting to improve the sucrose concentration of their crop.

Technical Abstract: Sugarcane (Saccharum spp.) is harvested during a 5-month period (October-March) in the Everglades Agricultural Area (EAA) of South Florida. The genetic and temporal variability of sugarcane sucrose concentration is well-established, but sucrose accumulation curves have not been reported for the Canal Point (CP) clones used in Florida since 1977. The objective of this study was to compare sucrose accumulation for recently-released clones and provide harvest schedule recommendations based on this information. Thirteen CP clones were sampled at 2-week intervals throughout 4 consecutive harvest seasons. Based on seasonal changes in cultivar ranking in sugar per ton, recommended harvest scheduling relative to October 14 are: Early-Season (0-50 days) CP 70-1133, CP 80-1743, CP 88-1762; Mid Seasons (50-100 days)CP 78-1628, CP 84-1198; Late-Season (100-150 days)CP 72-1210, CP 72-2086, CP 80-1827, CP 85-1382, CP 88-1508, CP 89-2377. Cultivar CP 89-2143 was ranked highest across all harvest periods and should be grown by Florida produces interested in improving the sucrose concentration of their crop.
