Accelerated Yield Technology (AYT™) System

A matrix of breeding technologies

The AYT™ system is a key part of a comprehensive plan to accelerate yield gain and broaden resistance to key diseases and insects by novel trait integration through our proprietary gene mapping, molecular breeding technologies and field testing protocols.

Pioneer has led the way in developing proprietary marker-assisted selection processes, most notably to protect soybean yield from harmful pests such as soybean cyst nematode, Phytophthora root rot, brown stem rot, sudden death syndrome and frogeye leaf spot.

In addition to employing molecular breeding technologies to protect yield, AYT marker technologies are now being used to boost the genetic yield potential of Y Series soybeans as well.

Using markers to select for yield

The AYT process starts with Pioneer researchers mining and analyzing their vast germplasm database to identify native genes associated with high yields.

Using molecular markers and patented molecular breeding techniques, plant scientists are able to track and select native genes associated with increased yields … and stack these genes in elite Pioneer varietal lines.

These breakthroughs, using non-transgenic biotechnologies, allow Pioneer researchers to quickly and efficiently "design" varieties carrying these yield-enhancing genes.

Blue markers with upper case letters symbolize genes associated with higher yields. Pioneer plant scientists, using proprietary AYT molecular breeding processes, combine the two parents to produce a progeny line that contains all six yield genes.
