Significantly genotypic differences and great variations were detected in grain β-amylase activity,β-glucan and protein fraction contents. The largest variation and highest average value of β-amylase activity were found in Hangzhou 2006-2007, while the trend of coefficient of variation was opposite to the mean content of β-glucan over different environments. Hordein content had the highest correlation coefficient with β-amylase activity among four protein fractions.
