A classic family tree represents the descendants of a person or another living being and is part of the genealogy (genealogy). In this form the descent of "all" varieties or even less, is impossible and fails for several reasons. The certified biologist Andreas Young notes the following: There are many individual ones Parent-offspring relationships, but not really family trees, since often only the mother is clear and that father is missing, as with the numerous seedlings of the Gouais Blanc (White Heisch). In principle, every seed (kernel) in a berry is a potential new grape variety, but it only becomes this when the kernel reaches the ground, germinates there and grows into a vine. Within a berry with 5 to 6 seeds, the fathers can be 5 to 6 varieties, depending on the pollen at the time blossom was blown on.
Family trees also simulate a chronological sequence and spatial limitation, but this does not have to be the case with grape varieties. The descendants of the Gouais Blanc may have emerged more or less simultaneously in one place from a few grapes or over several thousand years in several places. Uncles and aunts can be with the mother for example in the antiquity out Transcaucasia imported, while the children spontaneously grew from seeds at the new planting site of the mother variety. There is no generation sequence for grape varieties, as for mammals or humans, since they are potentially immortal and can often be grown in various places and over long periods. Spontaneous children of these varieties could be in Australia America South Africa and Europe arise, crossed with what just delivered pollen in the environment.
The grandchildren in Mixed sentence can pollinate the grandmother and aunt, creating a kind of incest. As long as the children and children's children are planted in a mixed set, there can be a lot of cross incest everyone with everyone. Dozens of fathers can use a mixed set to fertilize the individual flowers of a single vine as a pollen donor. If these seeds are sown, masses of step-siblings with a mother and many fathers arise and vice versa. The fathers of some are the mothers of others. The cultivated vines are yes hermaphrodite, And then it gets complicated with the family trees. One type of mother, several fathers, the father of one is the mother of the other, and all of this simultaneously during a week of flowering. Or the same game with the same parent varieties, but spread over thousands of years. Most of the cultivated varieties grown in Western Europe today belong to a relatively small group of so-called leading varieties such as Gouais Blanc. Pinot and Traminer as well as their spontaneous intersections back. See also a list of relevant keywords below grapevine,
