摘要
Abstract
In order to understand thegenetic basis for Zeleny sedimentation value (ZSV) of wheat,a doubled haploid (DH) population Huapei 3×Yumai 57 (Yumai 57 is superior to Huapei 3 for ZSV),and a linkage map consisting of 323 marker loci were used to search QTLs for ZSV.This program was based on mixed linear models and allowed simultaneous mapping of additive effect QTLs,epistatic QTLs,and QTL×environment interactions (QEs).The DH population and the parents were evaluated for ZSV in three field trials.Mapping analysis produced a total of 8 QTLs and 2 QEs for ZSV with a single QTL explaining 0.64-14.39% of phenotypic variations.Four additive QTLs,4 pairs ofepistatic QTLs,and two QEs collectively explained 46.11% of the phenotypic variation (PVE).This study provided a precise location of ZSV gene within the Xwmc 93 and GluD1 interval.which was designated as Qzsv-1D.The information obtained in this study should be useful for manipulating the QTLs for ZSV by marker assisted selection (MAS) in wheat breeding programs.关键词
