Rating Scale:

1-2 = Excellent
3-4 = Very Good
5-6 = Good
7-8 = Fair
9 = Poor
N/A = Not Available
A rating of “1” in standability is a soybean product with excellent standability. A rating of “1” in brown stem rot is a product with excellent tolerance to brown stem rot.

Soybean Cyst Nematode

R = Resistance
MR = Moderate Resistance
MR/MS = Moderate Resistance to Moderately Susceptible
S = Susceptible
# = Race 1, 3, 5, 9 or 14
A recent publication suggests that soybean cyst nematode populations should be described by a different method called HG type, instead of races. The Race 3 population used in our evaluations would be equivalent to “HG Type 0” and the Race 14 population would be equivalent to “HG Type 1.3” under the direction of the paper.

White Mold

White mold, caused by Sclerotinia sclerotiorum, is a soybean disease for which there is currently no known form of complete genetic resistance. Scores represent relative levels of tolerance to the disease, as outlined below.
<4 = Very Good
4 = Good
5 = Above Average
6 = Average
7 = Below Average
>7 = Poor

Canopy

Th = Thin
M = Medium
MB = Medium Bushy
B = Bushy

Phytophthora Gene Specific Resistance

Susc. = Susceptible
Rps1a denotes resistance to Races 1, 2, 10, 11, 13-18, 24, 26, 27, 21, 32, 36.
Rps1c denotes resistance to Races 1-3, 6-11, 13, 15, 17, 21, 23, 24, 26, 28-30, 32, 34, 36.
Rps1k denotes resistance to Races 1-11, 13-15, 17, 18, 21-24, 26, 36, 37.
Rps2 denotes resistance to Races 1-5, 9-29, 33, 34, 36-39.
Rps3a denotes resistance to Races 1-5, 8, 9, 11, 13, 14, 16, 18, 23, 25, 28, 29, 31-35.
Rps6 denotes resistance to Races 1-4, 10, 12, 14-16, 18-21, 25.
Rps7 denotes resistance to Races 2, 12, 16, 18, 19, 33, 35, 36.

Phytophthora Field Tolerance

Phytophthora field tolerance is a form of partial genetic resistance whereby the plant can maintain some level of productivity while infected with the pathogen. Phytophthora field tolerance scores represent relative responses to the following races of Phytophthora sojae.
Reaction to Phytophthora sojae Race 25 for products with Rps1a, Rps1c, Rps1k, Rps7.
Reaction to Phytophthora sojae Race 17 and/or Race 30 for products with Rps2, Rps3a, Rps6.
Phytophthora field tolerance scores indicate the following levels of tolerance:

<4 = Very Good
4 = Good
5 = Above Average
6 = Average
7 = Below Average
>7 = Poor

Pubescence

G = Gray
T = Tawny
LT = Light Tawny

Flower Color

P = Purple
W = White

Traits

CONV = Conventional
GENRR2Y = Genuity® Roundup Ready 2 Yield®
RR2X = Roundup Ready 2 Xtend®
SR = Sulfonylurea Ready (Sulfonylurea-based Herbicide Tolerance)
VG = Vistive® Gold

Chloride Sensitivity

Inc. = Includer
Exc. = Excluder
Excluder products have increased tolerance to elevated soil chloride levels compared to includers. Excluder products partition chloride in root systems and reduce the amount transported to ore sensitive above-ground tissue.

Southern Root Knot

R = Resistant
MR = Moderately Resistance
MS = Moderately Susceptible
S = Susceptible

Hilum Color

BL = Black
G = Gray
IB = Imperfect Black
IY = Imperfect Yellow
BR = Brown
BF = Buff
