Term for sexual reproduction in plants as well as in the vine. It occurs during flowering through fertilization and the subsequent sowing and cultivation of the grape seeds. However, due to the heterozygous nature of the vine, the offspring always differ from the original vine. This circumstance is taken advantage of in the new breeding of grape varieties. If, however, one wants to have genetically identical offspring(clones) for the purpose of creating a new vineyard or vineyard area, only vegetative reproduction (asexual reproduction), which is carried out professionally by grape nurseries, is possible. See also under breeding.
