Classification of E genotype groups by MG based on ex-PVP and private-company soybean lines. Reading across each row, the frequency of the E genotype is shown as a percentage of the total number of lines with that E genotype compared to all lines examined within a MG. For example, for MG III, 83% of the 126 lines had the e1-as E2 E3 genotype while 10% had e1-as e2 E3, and 8% had e1-as E2 e3-tr. The E genotypes with the highest percentage in each MG are bolded and highlighted gray. The alleles e1-nl and e1-fs are combined as e1-n*. a The E genotypes for the ex-PVP lines are grouped into MG 0-IX. b The E genotypes from the private-company lines provided by Dow AgroSciences are arranged by RM. Two E genotype groups were excluded because they only occurred with about 10% frequency in RM 0.0–0.9 (e1-n* E2 e3-tr and e1-n* E2 E3).
