Pioneer® Brand Soybeans Show Significant Yield Advantage Over Competitive Varieties in 2009

DES MOINES, Iowa, Nov. 23, 2009 - Soybean varieties from Pioneer Hi-Bred, a DuPont business, show a 1.3 bushel per acre yield advantage against all competitive varieties, according to data collected on 11,692 direct, on-farm field comparisons in 2009. Among these comparisons, Pioneer® brand soybeans with the original Roundup Ready® gene have on average a 2.7 bushel per acre yield advantage against varieties from competitors with the new Roundup Ready 2 Yield® technology.

The comparisons also show that Pioneer soybean varieties have a 2.8 bu/A yield advantage over Asgrow varieties with the Roundup Ready 2 Yield® technology.

Data for these comparisons were collected throughout all soybean production areas in North America -- and significant yield advantages for Pioneer soybean varieties were seen by growers within all regions.

"These yield results show what growers have learned to expect from Pioneer soybean varieties, that there is a significant difference between Pioneer and the competition in terms of yield and income," says Frank Ross, Pioneer vice president and regional director, North America. "We expect that the advantages for growers will continue into the 2010 growing season and beyond."

Much of the success for growers stems from Pioneer Y Series soybeans, introduced into the marketplace in the 2009 growing season. Pioneer Hi-Bred is adding 26 new soybean varieties to its lineup for 2010, providing more than 50 Y Series soybean varieties for growers across North America next season. In addition to enhanced yield, these new Y Series varieties offer growers strong agronomic traits and protection against yield-robbing pests such as soybean cyst nematode (SCN), sudden death syndrome (SDS), Phytophthora root rot, white mold and iron chlorosis.

"All new varieties are part of the Y Series lineup which continues to show yield, agronomic and defensive package advantages over competitors," Ross says. "This class of products will offer growers the opportunity for optimum yields for each field.

"For 2009 planting, nearly 8 million acres were planted with Pioneer Y series beans, the largest launch in company history," Ross adds. "We will have product to plant up to 20 million acres of Y series beans in 2010. Early invoicing - even with the significant harvest delay - indicates strong demand for these high-performing products."

The launch of the Y Series is the result of a proprietary matrix of traits and technologies Pioneer researchers have been developing and deploying to accelerate product development. Pioneer is employing its exclusive Accelerated Yield Technology (AYTTM) system and marker-assisted selection to boost the yield potential and improve the agronomic performance of these varieties. This harnesses the power of the Pioneer germplasm collection, strong bioassays, computing power and molecular breeding tools to drive genetic gain at unprecedented rates.
