In viticulture, this refers to the young vine germinated from an implanted grape seed. The germination of a seedling can take place independently in nature or can be consciously induced by man. In contrast to a genetically identical clone, which is produced by vegetative reproduction as a cutting (seedling), the seedlings produced by generative or sexual reproduction are genotypically fundamentally different. In comparison to other plant groups (e.g. trees), the grapevine is extremely heterozygous (cleaved) and cannot be propagated by seeds (grape seeds) in a variety-identical manner. The grape seeds carry the paternal genes transferred during fertilisation. For the appearance and the varietal typicity of the grapes it is completely irrelevant by which father variety the fertilization took place. These correspond to 100% of the type of the mother variety.
A seedling always shows a new combination of the parental inherited characteristics, which thus lead to a new grape variety. The up to five (rarely six) pips in a berry can produce very different varieties. For this reason, seedlings are not used for new planting in vineyards, but are only of interest in the breeding of new grape varieties. A seedling can be the product of a self-pollination (self-pollination), but it can also be the result of fertilisation with pollen from another vine. Such a variety, which is the result of self-pollination or cross-pollination and then germination of the grape seed, is called spontaneous (natural) crossing. Other names for this process are "fallen from seed" or open pollinated. The picture shows a young plant in the nursery. The soil is greened and the young shoots are protected against damage from game by plant tubes. See also flowering and grapevine.
