Sugarcane Cultivar Quick Reference Chart1
T. J. Schueneman, J. D. Miller, J. C. Comstock, and R. A. Gilbert2Introduction
This Sugarcane Cultivar Quick Reference Chart (see Table 1 ) is based on the best information available at the time of publication. What became quickly apparent while constructing this chart is that the micro-environment where a cultivar is grown, time of planting, seasonal weather pattern, and the cultural practices that immediately preceded the planting have an important bearing on the performance of a cultivar. The ratings presented in this chart are comparisons against the standard cultivar, CP 70-1133, and are composites from several evaluations.Before you select a new or different cultivar to be included in your cultivar mix, read the literature on that cultivar, talk to growers and research staff who have worked with it, and pay attention to how old the cultivar is and its disease problems. There are no fungicides available for field use on Florida sugarcane once it has been planted.
In order for a newly developed cultivar to be released for commercial production, it must exhibit good disease resistance. However, diseases mutate at an alarming rate, often overcoming plant resistance in two to ten years. A cultivar that has been released for ten years and is still resistant to rust (caused by Puccinia melanocephala H. Syd. and P. Syd.) probably does not have many years left in the commercial inventory. If a new cultivar has a fit in a grower's production plan at all, it should be planted as soon as possible after its release.
