Allelic variations in glutenin and puroindolines of 26 Korean wheat cultivars were evaluated to determine their effects on the physicochemical properties of flour and quality of white salted noodles. Cultivars carrying Pina-D1b and Pinb-D1b exhibited a coarser particle size of wheat flour and a higher ash and damaged starch content than those with Pina-D1a and Pinb-D1a. Glu-B1b, Glu-D1f, Glu-B3d and Pina-D1a alleles exhibited lower protein content than other alleles. Glu-A1c, Glu-B1b, Glu-D1f Glu-B3d, Glu-B3i and Pinb-D1b alleles appeared to be related to a lower SDS-sedimentation volume than other alleles. In dough rheological properties, Glu-A1a and Glu-D1d alleles showed a longer mixing time on the mixograph and maximum dough height but Glu-A3e and Glu-B3i alleles had a lower mixing time on the mixograph and a lower maximum dough height than other alleles at Glu-1 and Glu-3 loci. Regarding the quality of white salt noodles, about 10% of the variations in the hardness of cooked noodles were explained by Glu-A1 and Glu-B3 loci. Hardness rankings of cooked noodles were Glu-A1a > Glu-A1c > Glu-A1c at the Glu-A1 locus. Glu-B3h showed higher cooked noodle hardness (5.10 N) than other alleles at the Glu-B3 locus (< 4.66 N).
