The low content of the storage protein fraction hordein‐2 in the high‐lysine mutant Risø 56 is due to a mutation at or near the locus Hor2 coding for hordein‐2 polypeptides. The mutant gene is recessive in its qualitative effect on the electrophoretic banding pattern of hordein‐2, but co‐dominant with respect to the relative amount of the hordein fractions. Homozygous mutant seeds were about 10 % smaller than normal seeds. Nd linkage was detected between the mutant gene and the translocation between chromosomes 2 and 5 in mutant 56
