Data on juice quality and fibre content in the parental, F1, F2 and BC1 generations from crosses between four sugarcane (S. officinarum) cultivars and eight clones of S. spontaneum were recorded. Distributions of Brix, sucrose content, purity and fibre content in these generations were continuous and controlled by polygenes. Analyses of genetic variance indicated that additive genetic variance was more important than dominance genetic variance for all four characters. Narrow-sense heritability of these characters was moderate, hence selection should be effective to improve juice quality while lowering fibre content.
