The invention relates to a method for planting the monoploid of chrysanthemum. The inventive method finds the external shape mark of chrysanthemum pollen at single corn period, and uses said pollen to induce the callus to obtain the monoploid plant. The invention uses liquid medium to cultivate the pollen and pollen wall, to improve the differentiation ablity of callus. For the chrysanthemum withself-cross and sterility, the inventive pollen cultivation can obtain the monoploid and pure diploid, to be used in cross generation to obtain the better F1 generation quickly.
