Company participation in soybean variety testing programs in Illinois

This thesis analyzes location characteristics that affect companies' selection of testing regions in variety trials in Illinois. Agricultural R\&D from the private sector has surpassed the public sector as the main source of soybean varieties since the 1990s. Private participation of the variety testing programs forms a vital part of the service of providing public information and introducing new varieties. Using data from University of Illinois and Farmers' Independent Research of Seed Technologies from 2000 to 2015, I find that when controlled for varieties' maturity groups, regional characteristics exhibit limited influence over the selection process. One significant factor is locations' market potential, approximated by the proportion of planting acreage, which inversely affects the likelihood of a location being selected before the entrance of FIRST in 2008.
