Figure 4.

β-Amylase activity in offspring of the H. spontaneum × Adorra cross. Histogram showing the relative β-amylase activity of the H. spontaneum parent strain (bar 2) and 15 individual lines #1 to #15 (bars 3–17) from the H. spontaneum × Adorra cross normalized to the β-amylase activity of the parent cv Adorra (bar 1), calculated from the mean of six independent determinations. The error bars in the histogram represent the se values. The relative β-amylase activity of cv Adorra of 1.0 is equivalent to a β-amylase activity of approximately 15 units per 1 mg of protein.
