Über künstliche Kreuzung von Pisum sativum.

With Correns and de Vries, Tschermak brought Mendel’s work into prominence and confirmed it, although Tschermak may not have fully understood the Mendelian laws before he had read Mendel’s work. See also Tschermak’s first paper on the subject: “Über künstliche Kreuzung bei Pisum Sativum”, Ber. dtsch. bot. Ges., 1900, 18, 232-39.
