Pioneer Hi-Bred is expanding its seed research in central Iowa.

The company announced plans Wednesday for a new research facility in Dallas Center. The company says in a news release that it will support corn breeding, corn and soybean product testing and help farmers in western and central Iowa, eastern Nebraska and northwest Missouri.

Pioneer has had a research location in Dallas Center since 2004. Construction is to begin this month and be finished in the spring.

The new facility is the latest in a series of projects by Pioneer, including a $40 million research facility in Johnston that is expected to create 400 jobs.

Pioneer, which is headquartered in Des Moines, is a subsidiary of Wilmington, Del., chemical maker DuPont Co.
