The inheritance of two qualitative and two quantitative characters was studied in the F 3 and F 4 generations of a cross between two varieties of barley ( Hordeum vulgare L. emend. Lam.). It was shown that the two qualitative traits, aleurone color and level of free betaamylase, were each controlled by a single gene and that the two genes were independent. The two quantitative characters, nitrogen content and total beta‐amylase activity, were found to have high heritabilities and to be positively correlated. It was further discovered that nitrogen content and total beta‐amylase activity were both negatively correlated with level of free beta‐amylase. Progress from selection for these characters in F 3 could be expected, and genetic variability would remain in the selected lines.
