The seeds of tartary buckwheat were treated by chemica1 mutagen ethyl methane sulfonate(EMS) to construct a mutant population. The biological and agronomic characters were identified and analyzed in M2 generation. M3 generation materials were further verified. The results showed that six types of stable genetic mutants(big leaf, premature, late maturity,small grain, dwarf and albino plant) were gotten. There were no significant differences for the plant height, the branches of main stem, the nodes of main stem, the seeds per plant, the weight per plant and the 1000-seeds weight between the big leaf mutant, premature mutant and late maturing mutant. The plant height and the branches of main stem of the dwarf mutant and the weight per plant and the 1000-seeds weight of the small grain mutant were significant lower than the control materials, whereas the other characters were no significant differences with the control materials. Though the plant height of the albino plant was no significant differences with the control materials, the branches of main stem, the nodes of main stem, the seeds per plant, the weight per plant and the 1000-seeds weight were significant lower than the control materials.
