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.
