Seed companies look into high-starch corn for ethanol plants

Pioneer Hi-Bred International Inc., the world's largest seed corn supplier, is now gearing its seeds towards traits favourable for ethanol production as ethanol plants mushroomed all over the Midwest.

Of about 300 hybrids that Pioneer sells in North America, 135 yield grain with elevated levels of starch, the source of corn-based ethanol, said Russ Sanders, director of marketing for the Des Moines-based plant genetics company..

Some hybrids can yield up to 7 percent more starch, he said.

The company also tested its hybrids for how they perform in fermentation.

In addition, the company is using genetic engineering to increase hybrids' starch content and to develop other characteristics favoured by ethanol manufacturers.

While GM crops may cause concern because they are for consumption, the worries disappear when it comes to GM crops being used for fuel.

Other major seed corn companies, such as Monsanto-owned Dekalb are also busy pushing hybrids for ethanol-friendly traits.

Rick Brehm, president and chief executive officer of Lincolnway Energy, an ethanol company, said last year's surprising corn yields in drought-stricken areas of Iowa and Illinois help ease worries about dryness this year. He credits plant genetics companies for the crop's performance despite dry conditions.

Some farmers are raising corn that has higher starch content or other traits sought by ethanol manufacturers to receive better prices. However, such corn would require special storage, handling and testing, thus increasing costs industry experts said.
