GPI showed a significant correlation with the proportion of a flour
fraction of 1–10 lm (r = 0.540, p 6 0.05; this reflected that this
fraction was probably rich in glutenin. This is supported by a significant
positive correlation of a flour fraction of 1–10 lmwith LA SRC
(r = 0.50, p 6 0.05), which has been related to glutenin proteins.
