영문 초록

To investigate the genetic variation of high-and low-molecular-weight glutenin subunits (HMW-GS and LMW-GS), granule-bound starch synthase I (GBSSI) and puroindoline in 24 Korean wheat cultivars. At the HMW-GS compositions, three Glu-A1 alleles, five Glu-B1 alleles and three Glu-D1 alleles were identified. The high frequency of alleles at each locus was Glu-A1c allele (15 cultivars), Glu-B1b allele (16 cultivars) and Glu-D1f allele (16 cultivars). Four alleles were identified at the Glu-A3 and Glu-B3 loci and three at Glu-D3 locus and Glu-A3d, Glu-B3d and Glu-D3a were mainly found at each Glu-3 locus. Glu-A3d, Glu-B3d, Glu-D3b or c (4 cultivars, respectively) and Glu-A3d, Glu-B3d, Glu-D3a and Glu-A3c, Glu-B3d or h, Glu-D3a (3 cultivar, respectively) were predominantly found in Korean wheats. At the GBSS compositions, 2 waxy wheat cultivars, Shinmichal and Shinmi-chal1, showed null alleles on the Wx loci and other cultivars were wild type in GBSS compositions. At the puroindoline gene compositions, Korean wheat cultivars carried 3 genotypes, which 10 cultivars (41.7%) were Pina-D1a and Pinb-D1a, 11 cultivars (45.8%) had Pina-D1a and Pinb-D1b and 3 cultivars (12.5%) carried Pina-D1b and Pinb-D1a. These genetic variations could present the information to improve flour and end-use quality in Korean wheat breeding programs.
