Interpretive Summary:

Technical Abstract: Field populations of H. glycines are given race designations based on the percentage of females that develop on four differentials compared with Lee 64. This system provided critical information to extension and breeding programs when only Peking, PI 88788, and PI 90763 had been used to breed for H. glycines resistance. Cultivars or germplasm lines with four alternative resistance sources have since been registered. These lines, PIs 437654, 209332, 89772, and Cloud, differentiate H. glycines populations in discriminant function analysis. We propose an updated system that 1) includes four new differentials, 2) excludes Pickett, and 3) changes the convention of naming populations to allow easier addition of new, properly registered differentials.
