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.
