摘要

Doubled haploid wheat lines developed from a cross between a hard white winter wheat variety of normal starch endosperm and a waxy wheat variety were used to determine the effects of allelic variation in Wx-1, Glu-D1, Glu-B3 and Pinb-D1 loci on physiochemical properties of flour, noodle dough properties and textural quality of cooked noodles. Milling yield, damaged starch content, protein content and SDS sedimentation vol. of flour were influenced the most by allelic composition of Pinb-D1 loci, less by Wx-1 loci and least by Glu-B3. Wheat lines carrying Pinb-D1b or Glu-B3h alleles exhibited higher milling yield and damaged starch content of flour than those with Pinb-D1a and Glu-B3d alleles. Wheat lines carrying the Pinb-D1b allele were higher in protein content and SDS sedimentation vol. than those carrying Pinb-D1a. Mixograph water absorption was largely influenced by allelic composition of Wx-1 loci, whereas mixograph mixing time and mixing tolerance were predominantly determined by allelic composition of Glu-D1 loci. Amylose content and pasting properties of starch were mainly determined by allelic composition of Wx-1 loci with little influence by allelic compositions of Glu-D1, Glu-B3 and Pinb-D1 loci. Allelic composition of Wx-1 loci contributed 53.4% of the variation in optimum water absorption of noodle dough and 26.7% of the variation in thickness of the noodle dough sheet. Variation of 7.8% in optimum water absorption of noodle dough was contributed by the allelic composition of Pinb-D1 loci. Allelic composition of Wx-1 loci was responsible for 73.2, 74.4 and 59.6% in the variation of hardness, springiness and cohesiveness of cooked noodles, respectively. Cohesiveness of cooked noodles was also influenced by the allelic compositions of Glu-B3 and Pinb-D1 loci to a smaller extent.
