COVER

  

Perhaps it can be said that the Tedins, Hans and Olof, were responsible for introducing pea genetics to Scandinavia. The papers by Hans Tedin in Hereditas 1920-1928, and the one by Hans and Olof Tedin and Wellensiek, 1925, can be counted among the classic genetical papers on Pisum.

 Hans Tedin (1860-1930) was employed as plant breeder at the Swedish Seed Association, Svalof, from 1891 nearly until his death in 1930. He showed already in the 1890's that old landraces of self-fertilizing plants could be split up into a multitude of constant strains. This is said to be an important foundation for Johannsen's later work resulting in the pure line concept. After the rediscovery of Mendel, he started systematic genetic studies with Pisum.

 Olof Tedin (1898-1966), the son of Hans, also spent most of his professional career as a plant breeder with the Swedish Seed Association. He is famous in Sweden for his book (co-authored with Bonnier), "Biologisk variationsanalys" (Biological Analysis of Variance), a book which is noted for its clarity, simplicity, and logic.
