Some years ago I discover a small booklet (125p.) called «Les Blés de Semence» by F. Flandrin (Chef des Services Régionaux de l’O.N.I.C) and an old poster with more than 550 wheat and their pedigree. They were both published in 1949 in France and they give an impressive view of the huge exchange of genetic resources between breeders at the beginning of XXth century.
