The invention discloses a breeding method for a variety of zizania latifolia. The method is designed by adopting block experiments, double-season zizania latifolia and single-season zizania latifoliaare separately provided with block experiments, control groups are subareas individually arranged according to a local planting habit and management method, variety small areas are introduced in the block experiments, the variety small areas are randomly distributed, repetition is performed for three times, a seedling emergence period, planting time, tillering time, stem swelling start time and aharvest period of experimental varieties are recorded, field performance traits, occurrence conditions and prevention and control effects of pests and diseases, and product commodity traits of the experimental varieties are observed and recorded, crude zizania latifolia is harvested in a same harvest season in each area in batches, yields are combined, and a yield in each area is counted, and a main cultivation variety and a combination variety of the zizania latifolia suitable for large-scale production are screened. According to the method disclosed by the invention, through introduction, experiments and demonstration of a novel variety of the zizania latifolia and research of agronomic measures and environmental factors such as a fertilization technique, a cultivation density, cultivation time and water level regulation on the yield, quality and marketing period of the zizania latifolia, the novel variety of the zizania latifolia suitable for local planting is introduced and screened.
