Improving Effi ciency of Sugarcane Genotype Selection in Florida

The Canal Point (CP) sugarcane (Saccharum spp.) breeding program has developed highyielding cultivars for the organic soils of South Florida, but cultivar development has not been as successful for sand soils in this region.

The population estimates require the net missed persons by single year of age for each sex for all provinces and territories are required. While the coverage studies can provide reliable estimates of missed persons for each province and territory, the sample size is not large enough to...
