In viticulture, this is understood to mean the young vine germinated from a planted grape seed. The germination of a seedling can occur independently in nature or be deliberately induced by humans. In contrast to a genetically identical clone that results from vegetative propagation as a cutting (seedling), seedlings resulting from generative or sexual propagation are fundamentally different genotypically. Compared to other plant groups (e.g. trees), the grapevine is extremely heterozygous and cannot be propagated true to type via seeds (grape seeds). The berry seeds carry the paternal genes passed on at fertilisation. For the appearance and varietal typicity of the grapes, however, it is completely irrelevant which paternal variety was used for fertilisation. These correspond 100% to the type of the mother variety, regardless of this.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.Dr. Edgar Müller
