Abstract

This paper examines the development and adoption of Hard Red Winter (HRW), Hard Red Spring (HRS), and Soft Red Winter (SRW) wheat varieties in the major wheat producing states in the U.S. from 1919-1979. Both methods of varietal improvement and sources of new varieties have changed over the last 100 years. The purpose of this study is to analyze changes in the institution of origin, the geographical origin, and the varietal composition of vheat acreage in an attempt to better understand the development and adoption of new wheat varieties over the 60 years.
