Table 1.

ANOVA result of five Vis/NIR spectral groups displaying phenotypic variation for grain traits, % chalk, % amylose, ASV, bran color, width, length, and thickness among white grain samples from the AR09 environment. R² values are presented between PC1 components per wavelength group and grain quality trait.
