New AG34XF2 BRAND
- Tall plant with good growth on heavier soils; lodging potential in highly productive environments
- Resistance to soybean cyst nematode
- Very good field tolerance against Phytophthora rot
- Brown stem rot tolerance
Rating Scale: 1 = Excellent; 9 = Poor; - = None
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. For white mold and Phytophthora Field Tolerance, see specific rating scales on this page.
Soybean Cyst Nematode: R = Resistant; MR = Moderately Resistant; MR/MS = Moderately Resistant 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.

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 and Rps7.
Reaction to Phytophthora sojae Race 17 and/or Race 30 for products with Rps2, Rps3a and 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
White mold, caused by Sclerotinia sclerotiorum, is a soybean disease for which there is currently no know 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
Southern Root Knot: R = Resistant; MR = Moderately Resistant; MS = Moderately Susceptible; S = Susceptible
Chloride Sensitivity: Inc. = Includer; Exc. = Excluder
Excluder products have increased tolerance to elevated soil chloride levels compared to includers. Excluder products partition chloride in the root systems and reduce the amount transported to more sensitive above-ground tissue.
Plant Height: S = Short, MS = Medium-Short; M = Medium; MT = Medium-Tall; T = Tall
Growth Habit: D = Determinate; I = Indeterminate
Plant Type: M = Medium; MB = Medium-Bushy
Flower Color: P = Purple; W = White
Pubescene Color: G = Gray; T = Tawny; LT = Light-Tawny
Hilium Color: BL = Black; G = Gray; IB = Imperfect Black; BR = Brown; BF = Buff
Pod Wall Color: BR = Brown; TN = Tan
