What are BMR hybrids?

BMR hybrids produce forage that has reliably lower lignin content. BMR forage is typically about 10 percentage points higher in fibre digestibility than non-BMR corn hybrids since lignin is completely indigestible. BMR hybrids have been bred to deliver competitive forage yield and agronomic traits.

Brevant BMR hybrids can deliver improved profitability for your operation.

Additional Information

Corn Footnotes

IMPORTANT: Trait rating scores provide key information useful in selection and management of Brevant™ brand corn products in your area. Information and ratings are based on comparisons with other Brevant brand products, not competitive hybrids. Information and scores are assigned by Corteva Research Managers. Scores are based on period-of-years testing through 2019 harvest and were the latest available at time of printing. Some scores may change after 2020 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 Brevant.ca or contact a Brevant seeds retailer for the latest and most complete listing of traits and scores for each Brevant brand product.

  1. MARKET SEGMENT: Designations indicate product is also suitable for the following market: BMR – Brown Mid Rib Corn; AQ – Optimum® AQUAmax® ; 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.

  3. Grain Marketing: Single events from Qrome® and Optimum® AcreMax® XTreme products are approved for import into the European Union (EU), however the stacked events are not currently approved. 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.
  4. CRM (Comparative Relative Maturity): There is not an industry standard for maturity ratings so comparing products maturity and harvest moisture ratings between companies is usually difficult. Use the CRM rating to compare Brevant brand products with competitive hybrids of a similar maturity and harvest moisture. CRM ratings, and harvest moistures, for products within a family may vary slightly, depending upon the level of insect (ECB and CRW) infestation. Conventional and straight RR2 hybrids within a family will usually be 1-2 CRMs earlier than indicated, when insect infestations are moderate to heavy. One CRM difference is about 1/2 point of moisture difference at harvest.
  5. PHYSIOLOGICAL CRM: Measures differences in maturity to zero milkline stage. To help decide if a new product fits your area’s growing season, compare its physiological CRM to a corn product that you plant or one that is successfully used in your area.
  6. STRESS EMERGENCE: All corn products are expected to establish normal stands under average soil conditions. Stress emergence is a measure of the genetic ability or potential to emerge in the stressful environmental conditions of cold, wet soils or short periods of severe low temperatures, relative to other Brevant products. Ratings of 7-9 indicate very good potential to establish normal stands under such conditions; a rating of 5-6 indicates average potential to establish normal stands under moderate stress conditions; and ratings of 1-4 indicate the product has below average potential to establish normal stands under stress and should not be used if severe cold conditions are expected immediately after planting. Stress emergence is not a rating for seedling disease susceptibility, early growth or speed of emergence.
  7. DROUGHT TOLERANCE: Drought tolerance is a complex trait, determined by a platform’s ability to maintain yield in limited-moisture environments. A higher score indicates the potential for higher yields vs. other platforms of similar maturity in limited-moisture environments.
  8. GRAIN DRYDOWN: Compares corn products of a similar maturity for rate of kernel moisture loss after grain physiological maturity (zero kernel milkline). A lower score indicates slower drydown, possibly offering a wider opportunity for high-moisture grain harvest.
  9. TEST WEIGHT: Higher score indicates heavier test weight. 
  10. PLANT HEIGHT: 9 = Very Tall; 1 = Short.
  11. MID-SEASON BRITTLE STALK: Ratings determined by frequency and severity of stalk snappage at lower to middle stalk internodes from conditions usually favoured 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. 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 hybrid 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 hybrids with higher scores during period of susceptibility.

Disease and Pest Resistance Footnotes

DISEASE PRECAUTION: Growers should balance corn product yield potential, maturity and cultural practice selection against their anticipated risk of a specific disease and need for resistance. In high disease-risk conditions, consider planting products with at least moderate resistance ratings of 4 or higher to help reduce risk. When susceptible products with disease ratings of 1 to 3 are planted in conditions of high disease pressure, the grower assumes a higher level of risk. If conditions are severe, even products 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 product monitoring for stalk stability and timely harvest when warranted.

DISEASE & PEST RATINGS: 8-9 = Highly Resistant; 6-7 = Resistant; 4-5 = Moderately Resistant; 1-3 = Susceptible; Blank = Insufficient Data.

NORTHERN LEAF BLIGHT CAUTION: In conditions where Northern Leaf Blight (NLB) risk is high, growers should consider planting only products with at least moderate NLB resistance ratings of 4 or higher.

GIBBERELLA EAR ROT CAUTION: Ratings based upon visual symptoms at harvest. If Gibberella ear rot has caused significant damage in the past, growers should consider planting only products with at least moderate Gibberella ear rot ratings of 5 or higher.

GREY LEAF SPOT PRECAUTION: Avoid planting products with a lower grey leaf spot (GLS) rating in continuous corn fields that have a history of GLS infection, unless tillage operations that bury significant amounts of corn residue and inoculum are practiced.

SILAGE CRM (Comparative Relative Maturity): With no industry standard for silage maturity, comparing maturity and harvest moisture among corn-for-silage product is difficult. Brevant silage CRM ratings provide a relative comparison among Brevant product of rates at which product reach harvestable whole-plant moistures. It is on the same scale as the CRM rating provided for grain-corn product and does not represent actual days from planting or emergence to harvest moisture or half milkline.

SILAGE YIELD FOR MATURITY: Based on tons/acre (adjusted to 30% dry matter) from multi-year comparison of products within a maturity range not exceeding 5 silage CRM units.

STARCH AND SUGAR, %: Percent starch and soluble sugars (DM basis) in the whole-plant sample predicted by NIRS.

WHOLE PLANT DIGESTIBILITY: Based on whole-plant digestibility measurements (in-vitro cellulase) and nutrient profiles (starch, acid detergent fibre), as predicted by Near Infrared Reflectance Spectroscopy (NIRS).

FIBRE DIGESTIBILITY: Enzymatic estimate of percent degradable neutral detergent fibre (NDF) as a percent of total NDF in whole-plant sample, predicted by NIRS.

SILAGE CRUDE PROTEIN: Based on the amount of crude protein in the whole plant, predicted by NIRS.

MILK OR BEEF PER ACRE: 9 = Outstanding; 1 = Poor. Based on University of Wisconsin MILK2006 utilizing silage, nutrient content and digestibility.

MILK OR BEEF PER TON: 9 = Outstanding; 1 = Poor. Based on University of Wisconsin MILK2006 utilizing silage yield, nutrient content and digestibilit
