The method comprises the following concrete steps: a zedoary breeding target is determined first; an excellent individual plant is selected from wild or cultivated population materials; the selected excellent individual plant is subjected to indoor plant test after harvest; an elected individual plant is propagated into a strain; an elected excellent strain is propagated into a breed strain after indoor plant test; then an excellent breed strain and other seeds for production are subjected to variety comparative test; and the excellent breed strain is finally bred into a new excellent variety. The growth vigor and feature of plants, the weight of the individual zedoary plant and zedoary oil content are taken as election indices all the time in the whole breeding process.
