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
