Abstract
Hordein polypeptide patterns in barley seeds are known to be controlled by structural genes at 2 loci, Hor-1 and Hor-2, on chromosome 5. Two-dimensional and high resolution one-dimensional electrophoretic analyses of seeds of F2 and doubled haploid progenies of four intervarietal crosses gave no evidence of recombination within these loci. Genetic analysis of the progenies showed that Hor-1 is 0·161 + 0·026 centimorgans from Hor-2 and the mildew resistance locus, Mla, lies between them, 0·064 ± 0·020 centimorgans from Hor-1 and 0·082 + 0·024 centimorgans from Hor-2.
