摘要：Using responses from a mail survey conducted among 203 South Dakota grain elevator managers in 2002, we analyzed the degree to which the elevators were prepared to segregate non-transgenic from commodity grains. Only 17 and two percent reported having buyers inquire about segregated non-transgenic or identity preserved corn, and such soybeans, respectively. Among those handling corn (soybeans), 53 (58) percent were willing to participate in non-transgenic corn (soybean) markets at an average premium of 28 (37) cents per bushel. It appears that one in five elevators are able to participate in segregating non-transgenic and commodity grains without additional capital outlays.
