摘　　要：以138份重组自交系群体为材料,并利用已构建的高密度遗传图谱对人工合成六倍体小麦SHWL1的紫色花药目标性状进行遗传定位。结果表明,该目标性状为单基因遗传,且被定位于染色体3D,该基因与R基因、Pal基因及Dfr等基因毗邻或具有等位性。A population contained 138 recombinant inbred lines and a high density genetic mapping were used to precisely detect genetic allele controled purple anther. The genetic analysis results indicated that the purple anther was a monogenic trait in SHW-L1, and this single gene was located on chromosome 3D, which might be the same alleles or at a short distance from R, Pal, and Dfr genes on 3D.
