The DuPont technology—Accelerated Yield Technology (AYT)—uses proprietary molecular breeding techniques to rapidly scan and identify genes that increase yield and then incorporate them into elite soybean genetics.

Until now, molecular breeding techniques used by the seed industry have only produced single-gene defensive traits in commercial varieties. There are multiple genes in complex networks that determine the final yield level achieved. AYT builds upon DuPont molecular breeding techniques by allowing researchers to simultaneously select multiple genes to significantly boost yields. AYT is not transgenic so soybeans developed from this process are not subject to additional regulatory approvals.

The first AYT varieties are higher yielding versions of the newest Pioneer elite soybean genetics. Pending final trial results this fall, Pioneer hopes to introduce an AYT version of Pioneer brand 94M80, which set the world record soybean yield of 139 bushels per acre in 2006. New unique genetics are also being developed using AYT and other molecular breeding techniques.

Full implementation of AYT combined with molecular breeding technologies will enable Pioneer to make a new class of soybeans that has unprecedented yield potential relative to anything we have ever seen. These technologies allow us to incorporate a complete package of offensive and defensive characteristics that could make 100-plus bushel soybean yields a common occurrence in the very near future.

Separately, DuPont also announced a pledge of $1 million to the Iowa State University (ISU) New Century Farm, the first research effort in the United States to focus on producing cellulosic ethanol on the farm. The research efforts also will focus on enhancing the production, processing and utilization of feedstocks for biofuels and biomaterials.
