Abstract

IThis article: a) analyzes the evolution of biological innovations in wheat varieties from the middle of nineteenth century to the end of twentieth century, in Britain, France, Spain and Italy, and b) shows that when we consider that aspect of the technological changes in agriculture, it explains better the evolution of grain yields in that cereal. The article also shows the impact of the following four variables on these innovations: scientific advances in biology; and other environmental, institutional and technological factors. The article also provides a new indicator on the evolution of these innovations, which can be particularly useful to better determine the distribution in time of short-stemmed and semi dwarf wheat: wheat production per weight unit of the hay harvested.
