摘　　要：采用SSR技术对沪 95 2 6 39和 91冬 2 7携带的两个新的矮秆基因进行了分子标记。在大麦 4H染色体的长臂上 ,发现SSR标记位点HVM 6 7同时与这两个新的矮秆基因连锁 ,距 91冬 2 7的较近 ,约 10 0cM ,离沪 95 2 6 39的较远 ,为2 3 3cM。初步绘制出大麦 4H染色体上矮秆基因与SSR标记位点的遗传连锁图谱。Two new dwarfing genes in Hu95-2639 and 91D27 were tagged molecularly with simple sequence repeats(SSR). SSR marker HVM67, which was known to be on the long arm of barley chromosome 4H, was found to link to the new dwarfing gene in 91D27 by 10 6cM, to another in Hu95 2639 by 23 3cM. A linkage map of the two new dwarfing genes to SSR markers was established preliminarily.
