摘要: In this report, we present a set of 104 ILs with 18 alleles for five glutenin loci. They were developed from crossing and backcrossing 64 varieties as donor parents to Yanzhan 1 as recurrent parent. The effects of the 18 alleles on nine dough quality parameters were evaluated in a similar background using these lines. The results showed that Glu-A1a produced the highest SDS-sedimentation volume (Ssd), midline time x=8 width (MTxW), mixing tolerance (MT) and the lowest weakening slope (WS). At the Glu-B1 locus, Glu-B1f produced the highest values for all quality parameters but WS. At the Glu-D1 locus, Glu-D1d was the best for Ssd, grain hardness (GH), midline peak width (MPW), MTxW and MT. The positive effects of Glu-B1f on GH and Glu-B3b on Ssd were mainly from the effect of GPC. Overall, 5 interactive loci and 13 interactive alleles were found to be significant. No negative interaction between high quality glutenin alleles was detected. The preferred allele combinations for breeding were recommended based on the additive and interactive effects. Our results suggest that the ILs with multiple alleles are ideal genomic stocks for evaluating the effects of alleles on some traits and for pyramiding favorable alleles in breeding wheat varieties.
