The present invention relates to hybrid Lactuca sativa seeds which have a male sterile genotype and which are heterozygous for at least one distinct gene which confers a detectable phenotype on the plants derived from these seeds. 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.
La présente invention se rapporte à des graines de Lactuca sativa hybrides, présentant un génotype mâle stérile, et hétérozygotes pour au moins un gène distinct conférant un phénotype détectable aux plantes issues de ces graines. L'invention se rapporte également à un procédé de production de graines Lactuca sativa hybrides, comprenant une étape de culture dans un milieu fermé, de plantes phénotypiquement mâles stériles et de plantes phénotypiquement mâles fertiles, une étape de pollinisation par des diptères introduits dans le milieu fermé à l'époque de la floraison des plantes et une étape de récolte des graines produites par les plantes mâles stériles.
