An analysis of the association of 10 chemical and agronomic characters with purity in three sugarbeet ( Beta vuigaris L.) genotypes was used to develop models to identify the components having the greatest effect on purity. Potassium, betaine, and Na followed by NO 3 ‐N, amino N, and sucrose were the most important variables in the 12 best models developed to explain purity. R 2 values (percentage of ascribed variation in purity) for these 12 best models ranged from 89.5 to 94.7%. Soluble nonsucrose constitutents increased in quantity from high plant population density to low density, but this linear change did not greatly affect models constructed to account for juice purity either at regular or low N fertility.
