Trait rating scores provide key information useful in selection and management of Pioneer® brand products in your area. Information and ratings are based on comparisons with other Pioneer brand products, not competitive products.  Information and scores are assigned by DuPont Pioneer Research Managers. Scores are based on period-of-years testing through 2014 harvest and were the latest available at time of publishing. Some scores may change after 2015 harvest.  Scores represent an average of performance data across areas of adaptation, multiple growing conditions, and a wide range of both climate and soil types, and may not predict future results. All products within a corn hybrid family receive the same score unless observations indicate a significant difference. Individual product responses are variable and subject to a variety of environmental, disease and pest pressures.  Please use this information as only one component of your product positioning decision. Refer to or contact a Pioneer sales representative for the latest and most complete listing of traits and scores for each Pioneer brand product


9 = Excellent; 1 = Poor; Blank = Insufficient Data.


The DuPont™ ExpressSun® trait provides resistance to Tribenuron methyl. WARNING: The DuPont™ ExpressSun® trait will safeguard this hybrid ONLY against applications of Tribenuron methyl, when applied at labeled rates. The DuPont™ ExpressSun® trait WILL NOT safeguard this hybrid against applications of other herbicides which require a different herbicide resistance trait. Always read and follow herbicide label instructions prior to use. APPLICATIONS OF INCOMPATIBLE HERBICIDES TO THIS HYBRID COULD RESULT IN TOTAL CROP LOSS.

9 = Excellent; 1 = Poor; Blank = Insufficient Data.


Grower should balance hybrid yield potential, hybrid maturity and cultural practice against anticipated risk of a specific disease and need for resistance. In high disease risk conditions, consider planting hybrids with at least a rating of 6 or higher to help reduce risk. When hybrids with disease ratings of 1 to 5 are planted in conditions of high disease pressure, the grower assumes a higher level of risk. If conditions are severe, even hybrids rated as resistant can be adversely affected. Independent of yield reduction, diseases can predispose plants to secondary diseases such as stalk rots. This requires individual field and hybrid monitoring for stalk stability and timely harvest when warranted.


9-8 = Highly Resistant; 7-6 = Resistant; 5-4 = Moderately Resistant; 3-1 = Susceptible; Blank = Insufficient Data.


With no industry standard for maturity ratings, comparing hybrid maturity and harvest moisture ratings between companies is usually difficult. Use the RM rating to compare Pioneer hybrids of a similar maturity and harvest moisture.


Ratings taken when first true leaf is visible.


Short stature is desirable. 9 = Short; 1 = Tall.


To our knowledge, there are no fully resistant hybrids in this industry. However, differences exist in the ability to tolerate insect pressure. These scores reflect those differences. Heavy midge pressure can cause extensive damage to any hybrid.


Indicates downy mildew resistance to the races identified.
