The invention also relates to a method for producing hybrid Lactuca sativa seeds, comprising a step of cultivating phenotypically male-sterile plants and phenotypically male-fertile plants in a closed medium, a step of pollinating by means of dipterans introduced into the closed medium at the time the plants are flowering, and a step of harvesting the seeds produced by the male-sterile plants.
