Sugarcane Genotype Selection in Florida - The Canal Point (CP)
sugarcane (Saccharum spp.) breeding program has developed high-
yielding cultivars for the organic soils of South Florida, but
cultivar development has not been as successful for sand soils
in this region. Our objectives were to improve final-stage
(Stage 4) selection efficiency of this program by assessing
interactions among genotypes, soils, and locations and other
sources of variation and by comparing the relationship between
repeatability and number of replications as a measure of
precision for testing sugarcane genotypes on sand and muck
soils. Sources of variation were partitioned for plant-cane,
first-ratoon, and second-ratoon data, from 7 yr and five CP
series in Stage 4 tested at eight locations on muck soils and
two locations on sand soils. Variation related to genotype ×
location (soil) was highly significant for can
