Abstract

Abstract

The inheritance of two qualitative and two quantitative characters was studied in the F8 and F, 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.~ could be expected, and genetic variability would remain in the selected lines.
