No cultivar name of record
This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
The invention relates to a new and distinct hybrid Rubus variety which has been designated the Tayberry. The subject variety was formed by the crossing of the octoploid blackberry Aurora with a tetraploid raspberry pollen parent known as 626/67. This variety resembles the Loganberry in some respects, but is superior to it with respect to fruit size, yield, fruit color, mode of presentation of fruit, and ease of propagation by root cuttings.
