Product performance in water-limited environments is variable and depends on many factors such as the severity and timing of moisture deficiency, heat stress, soil type, management practices and environmental stress as well as disease and pest pressures. All products may exhibit reduced yield under water and heat stress. Individual results may vary. 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 Pioneer Research Managers. Scores are based on period-of-years testing through 2020 harvest and were the latest available at time of printing. Some scores may change after 2021 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 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 www.pioneer.com or contact a Pioneer sales professional for the latest and most complete listing of traits and scores for each Pioneer brand product and for product placement and management suggestions specific to your operation and local conditions.

AM - Optimum® AcreMax® Insect Protection system with YGCB, HX1, LL, RR2. Contains a single-bag integrated refuge solution for above-ground insects. 

AMXT (Optimum® AcreMax® XTreme) - Contains a single-bag integrated refuge solution for above- and below-ground insects. The major component contains the Agrisure® RW trait, the Bt trait gene, and the Herculex® XTRA genes. Always follow and adhere to the Corteva Agriscience Product Use Guide (“PUG”), which requires that you take all affirmative steps within your control to appropriately manage and confirm your grain buyer’s acceptance of the grain being sold and only deliver grain to a purchaser or grain handler that agrees grain and by-products will be marketed in domestic food and feed and export markets where such products are authorized for the specific use. For additional information about the status of regulatory authorizations for these products, including the individual components as well as the trait stacks, please visit biotradestatus. com or visit seedinnovation.ca/ hybrid to review the EU approval status for specific hybrids marketed in Canada. 

Q (Qrome®) - Contains a singlebag integrated refuge solution for above- and below-ground insects. The major component contains the Agrisure® RW trait, the Bt trait gene, and the Herculex® XTRA genes. Always follow and adhere to the Corteva Agriscience Product Use Guide (“PUG”), which requires that you take all affirmative steps within your control to appropriately manage and confirm your grain buyer’s acceptance of the grain being sold and only deliver grain to a purchaser or grain handler that agrees grain and by-products will be marketed in domestic food and feed and export markets where such products are authorized for the specific use.

Hybrid family identifies products that have the same base genetics. Manage products within the same family similarly

Designations indicate product is also suitable for the following market: HAE – High Available Energy (Pork and Poultry Feed); HTF – High Total Fermentables (Dry-Grind Ethanol); HES – High Extractable Starch (Wet Milling); WX – Waxy; WH – White food corn; YFC – Yellow food corn; AQ – Optimum® AQUAmax® product; BMR – Brown MidRib Corn.

Measures differences in growing degree units (GDUs) required to zero milkline stage. To help decide if a new product fits your area’s growing season, compare its GDUs to physiological maturity to a product that you plant or one that is successfully used in your area

Ratings determined by frequency and severity of stalk snappage at lower to middle stalk internodes from conditions usually favored by rapid or optimum growth. Relative response of products can be affected by planting date, stage of growth, rate of growth, wind severity and other variables. Scores derived from both natural observations and artificial evaluation immediately prior to tasseling.

BRITTLE STALK PRECAUTION: In NOTE: Scores do not reflect snappage enhanced by or due to herbicide interaction. The use of growth regulator herbicides such as 2,4-D and dicamba can increase the brittle snap potential of corn products. Products with lower brittle stalk ratings will require more caution and have a higher risk associated with the use of growth regulator herbicides. Early application, proper rates and application methods, along with both product and herbicide selection can help reduce this risk. 

BRITTLE STALK PRECAUTION: In areas with higher potential for brittle stalk breakage, growers must balance the risk of planting products with brittle stalk ratings of less than 4 against the overall performance of more resistant products with higher ratings. All products have a period of susceptibility to brittle stalk. Products with below average ratings may have a longer period of susceptibility, or may experience more severe breakage relative to products with higher scores during period of susceptibility

8-9 = Highly Resistant; 6-7 = Resistant; 4-5 = Moderately Resistant; 1-3 = Susceptible

SILAGE CRM (Silage Comparative 

Relative Maturity):

 With no industry standard for silage maturity, comparing maturity and harvest moisture across various companies’ corn-for silage hybrids can be difficult. Pioneer silage CRM ratings provide a relative comparison among Pioneer® brand products of rates at which products reach harvestable whole plant moistures. It is on the same scale as the CRM rating provided for grain corn products and does not represent actual days from planting or emergence to harvest moisture or half milkline. 

Based on whole-plant yield per acre (adjusted to 35% dry matter) from multi-year comparison with other products within a maturity range not exceeding 5 silage CRM units.
