Genetic control of hordein polypeptides in kernels of spring barley (Hordeum vulgare L.) high-lysine mutant C-67-7
Languages of publication
The subject of the studies were F1 and F2 hybrids originating from reciprocal crosses of the highlysine mutant C-67-7 and cultivar Miranda, the forms with different hordein polypeptide spectra. The method of SDS gel electrophoresis was used for an analysis of the main hordein fractions, hordein-1 and hordein-2, from single kernels of barley. It was found that polypeptide spectra of hordein-1 and hordein-2 of the high lysine mutant C-68-7 are determined by codominant alleles at two loci, which are moderately linked.
