Product responses are variable and subject to any number of environmental, disease and pest pressures. Please use this information as only part of your product positioning decision. Individual results may vary.

Trait ratings provide key information useful in selection and management of Pioneer® brand products in your area. Scores are based on testing through 2018 harvest and were the latest available at time of printing. Some scores may change after 2019 harvest. Information and ratings are based on average performance across area of adaptation under normal conditions, over a wide range of both climate and soil types, and may not predict future results. Refer to www.pioneer.com/products/soybeans 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.

NUMERIC RATINGS


*NEW product.

† New Product. Not Available for sale until 2020 orders and invoicing are available. Quantities may be limited.

** All Pioneer products are varieties unless designated with LL, in which case some are brands.

9 = Excellent; 1 = Poor; Blank = Insufficient Data or variety not tested for that particular trait.
** Ratings denoted with a double asterisk (**) reflect preliminary data subject to change when additional data becomes available.

Components of LumiGEN™ technologies for soybeans are applied at a Corteva Agriscience™, Agriculture Division of DowDuPont production facility, or by an independent sales representative of Corteva Agriscience or its affiliates. Not all sales representatives offer treatment services, and costs and other charges may vary. See your sales representative for details.

NUMERIC RATINGS


9 =
 Excellent; 1 = Poor; Blank = Insufficient Data or variety not tested for that particular trait.

 

RELATIVE MATURITY

Shows the relative maturity group rating, with the first digit representing the general maturity group, and the second digit showing relative maturity within the group on a scale of 0 to 9, with 0 early and 9 late. For example, a soybean product with a relative maturity rating of 17 would be a mid-late product in Group 1 maturity.

 

FIELD EMERGENCE

Rating based on speed and strength of emergence in sub-optimal temperatures. 1-3 = Below Average; 4-6 = Average; 7-9 = Excellent.

 

PHYTOPHTHORA RESISTANCE GENE

(-) = No specific gene for resistance.

Rps1^^ = Contains Rps1c or Rps1k Phytophthora resistance.
Rps 1a = Provides resistance to races 1, 2, 10, 11, 13-18, 24, 26, 27, 31, 32 & 36.
Rps 1c = Provides resistance to races 1-3, 6-11, 13, 15, 17, 21, 23, 24, 26, 28-30, 32, 34, 36.
Rps 1k = Provides resistance to races 1-11, 13-15, 17, 18, 21-24, 26, 36, 37.
Rps 6 = Provides resistance to races 1-4, 10, 12, 14-16, 18-21, 25, 28, 33-35.
Rps 3a = Resistant to races 1-5, 8-9, 11, 13-14, 16, 18, 23, 25, 28-29, 31-35, 39-41, 43-45, 47-52, 54…
Rps 3c = Resistant to races 1-4, 10-16, 18-36, 38-54…

 

PHYTOPHTHORA FIELD TOLERANCE

Products with high tolerance scores have demonstrated an ability to thrive in the presence of Phytophthora races to which they lack specific resistance. In some products, tolerance is expressed only after the early seedling growth stage, making such products susceptible to damping off during emergence and early seed growth.

 

BROWN STEM ROT MARKER PREDICTED

HT = Highly Tolerant; MT = Moderately Tolerant; MS = Moderately Susceptible.

 

WHITE MOLD

Scores based on Pioneer research observations of comparative white mold tolerance among various soybean products across multiple locations and years. All products are capable of developing white mold symptoms under severe infestations. To our knowledge, there are no totally resistant products in the industry. However, differences exist in the ability of products to tolerate white mold (i.e., the rate at which the infection develops and the extent of damage it causes). These scores reflect those differences.

 

SCN RESISTANCE SOURCE

There are three sources of genetic resistance to SCN currently deployed in the marketplace: PI88788; PI548402 (also known as Peking); PI437654 (also known as Hartwig); R = Resistant to SCN but the source of that resistance is not yet identified.

 

SOYBEAN CYST NEMATODE [SCN]

Resistance to each of the major SCN races is scored on a 1-9 scale. 9 = Excellent resistance; 8-7 = Very good resistance; 6 = Good resistance; 5 = Average resistance; 4 = Below average resistance; 3-2 = Susceptible; 1 = Highly susceptible; to the specific race indicated.

 

APHID ANTIBIOSIS

A type of resistance that measures the plant’s ability to naturally reduce the rate of growth, survival and reproduction of soybean aphids on soybean plants. Antibiosis is measured by comparing the rate of aphid reproduction on different products. Since no products currently on the market offer complete resistance to aphids, growers should use these antibiosis ratings as a pest management tool (not a product selection tool) to help determine field scouting and insecticide application priorities. “E” = exceptional, “AA” = above average, “A” = average and “BA” = below average antibiosis ratings. For example, products with exceptional ratings display much lower aphid reproduction compared to products with average and below average ratings

 

CHARCOAL ROT

A fungal disease that is enhanced by hot and dry conditions, especially during reproductive growth stages. Scores based on Pioneer research observations of the comparative ability to tolerate infection from the charcoal rot pathogen among various soybean products.

 

STEM CANKER GENE

“9” = provides resistance. “5” = provides moderate resistance. “1“ = no specific gene for resistance.

 

CERCOSPORA

A fungal disease that is enhanced by wet periods followed by hot and dry conditions, especially during reproductive growth stages. Scores based on Pioneer research observations of the comparative ability to tolerate infection from the Cercospora kikuchii pathogen among various soybean products.

 

CHLORIDE SENSITIVITY

This score tracks the ability of the soybean product screened for this trait to be able to grow and have normal yields in soils that have high levels of chloride salts.

 

CANOPY WIDTH

9 = Extremely bushy; 1 = Very narrow.

SHATTERING


9 =
 Excellent tolerance to shattering; 1 = Poor tolerance to shattering.

 

PLANT HEIGHT FOR MATURITY

9= Tall; 1 = Short.

 

PLANT HABIT

IND = INDETERMINATE-type soybeans grown in Group 00-4 regions. These plants typically continue to grow as they flower, resulting in a longer pod fill time. You may find nearly mature seeds at the bottom of a plant that is still flowering at the top. DET = DETERMINATE soybeans grown in Group 5 and later maturities. These plants typically stop growing once they begin to flower, and all flowering occurs within a more defined timeframe.

 

FLOOD TOLERANCE

Tolerance to standing water or saturated soils which are typically found at the low end of surface irrigated fields or in the low lying areas of fields after a heavy rain event. The score is a measure of the variety’s potential to continue normal growth and photosynthesis when placed under those environmental conditions for up to one week.

 

% PROTEIN AT 13% MOISTURE

Compare data within table only. Values can vary widely by growing season and region.

 

% OIL AT 13% MOISTURE

Compare data within table only. Values can vary widely by growing season and region.

 

SEED SIZE RANGE

Expressed in seeds per pound under normal growing conditions. Range is calculated over multiple years and locations. Since seed size may vary by growing season and region, check the "seeds/pound" information printed on the bag.

 

FLOWER COLOR

P = Purple; W = White.

 

PUBESCENCE COLOR

T = Tawny; G = Gray; L = Light tawny; M = Mixed.

 

HILA COLOR

BL = Black; BR = Brown; TN = Tan; G = Gray; IB = Imperfect black; BF = Buff; Y = Yellow (Clear); M = Mixed.

 

POD COLOR

BR = Brown; TN = Tan.

 

SEED COAT LUSTER

S = Shiny; D = Dull; I = Intermediate.

 U.S. patents, Plant Variety Protection Act (PVPA) applications and certificates, or other limitations on use may be used to protect Pioneer brand soybean products from unauthorized growing, selling or use of the seed. These protections help assure that growers will continue to have access to new and improved products through the research efforts of plant scientists in the years ahead.
