Technical Abstract: Sugar and fiber are the two most important products of sugarcane. Deposition changes in sucrose and fiber in cane stalks as sugarcane matures is important in evaluation of variety performance in variety development program. Nine Canal Point (CP) clones were used to determine the patterns of change in both sugar and fiber contents in cane stalks during plant maturation. Measurements of Brix, sucrose, and fiber were based on three 5-stalk samples harvested from both plant cane and first ratoon crops every 6 weeks. These measurements were regressed on time of sample. Results indicate that Brix and sucrose were best described by quadratic regressions while fiber changes were linear. The magnitude of the regression constants varied among clones. Different clones approached their peaks of either Brix or sucrose content at different sampling times while the fiber content increased steadily with time. Data on the maximum sucrose content and the corresponding fiber level may allow us to develop sugarcane varieties with balanced high sugar recovery and high bagasse yield percent cane.
