Hop pedigree data

This is a tab-delimited .txt file detailing what is known about pedigrees for hop varieties and breeding materials, mainly from British, German, and USDA breeding programs. The data start with Salmon's release of Brewer's Gold in 1934 and end with the USDA release of Vista in 2021. The data contain named varieties and parents (where known), including a substantial number of selections with unknown male parentage. The pedigrees are based on published data and conversations with researchers in the US, Germany, Japan, and UK. Hops from breeding programs in Australia, New Zealand, Germany, and private breeders in the US are under-represented due to their proprietary tendencies. The information here were used to generate a poster available for sale from the UMN Bookstore (SKU: 2820000084149), a smaller version of which is available from the UMN Digital Conservancy (https://hdl.handle.net/11299/267835). Additional information is contained on these posters, including indications of which varieties are dwarf, similarities of Columbus, Tomahawk, and Zeus, and equivalence of Styrian Golding, US Tettnanger, and Fuggle.
