Heterosis in Ornamentals

Abstract

When Shull in 1911 made known his ideas on hybrid vigour in plant breeding and introduced the name “heterosis” for this conception, there had already been commercially released a variety of Begonia semperflorens by Benary Seed Company from Erfurt/Germany, which carried all the criterions of a real “heterosis” variety, i.e.
  • hybrid vigour in connection with optimal uniformity;

  • a heterozygosity giving rise to a strong segregation of characters in F2 and consequently preventing any illegal reproduction;

  • the necessity of being reproduced by constant new crossing of two parental lines bred to homozygosity.
