DP-32138-1
Hybrid maize seed production requires crossing two inbred parent lines to produce hybrid seed sold to growers. The female inbred parent must be prevented from shedding pollen to avoid self- pollination that reduces hybrid seed quality and compromises hybrid yield potential.

The 32138 SPT maintainer is used as a pollinator to propagate the seed of male-sterile female inbred parent lines.

The female inbred parent seed produced using this technology does not contain the 32138 SPT insertion and consequently, hybrid seed produced using these male-sterile female inbred parents does not contain the 32138 SPT insertion and hence are non-transgenic for SPT.
