Technical Abstract: In south Florida, sandy soils planted with cane are highly variable in nutrient contents and moisture. This variability affects the selection of new sugarcane genotypes, some genotypes are dropped during the selection process due to its low yields because they are planted in sections of the field with low nutrients and/or moisture. Some statistical methods can be used to adjust yield values of genotypes based on that soil variability. The objective of this study was to evaluate two statistical methods to improve the selection efficiency in the first clonal stage within the Canal Point sugarcane breeding program for sandy soils. Six hundred twenty-eight experimental genotypes were used in the study. Values of number of stalks, weight, Brix, and Pol were adjusted with two methods and used to estimate the tonnes of cane per hectare (TCH), commercial recoverable sucrose (CRS), and tonnes of sugar per hectare (TSH). Adjusting for soil variability with the statistical methods permitted to select the clones with the highest TCH and TSH. These results suggest that adjusting for variability could be suitable to improve the efficiency of selection in sandy soils during the earliest stages of the sugarcane breeding program in south Florida.
