Patent ID: 8227662

Claim:
A method of breeding soybean for aphid resistance, comprising, a) providing, i) a first soybean plant comprising aphid resistant germplasm, wherein said first soybean plant is selected from the group consisting of accession PI567598B, accession PI567543C, accession PI567541B, accession PI567597C, line E06902 deposited under ATCC accession No: PTA-8794, and progeny thereof, ii) a second soybean plant, wherein said second soybean plant is an elite soybean plant, and iii) a molecular marker, wherein said marker is selected from the group consisting of a marker that identifies a region of a linkage group, wherein said linkage group is selected from the group consisting of F, M, and J, and a DNA marker, wherein said DNA marker is selected from the group consisting of Satt343, Satt193, Satt649, Satt150, Satt435, Sat — 299, Sat — 339, Satt414, Satt654, Satt596, Satt622, Satt380, Satt596, Satt456, Satt183, Satt215, Sat — 366, and Sat — 350; and b) crossing said first soybean plant with said second soybean plant for breeding a progeny soybean plant with aphid resistance, and c) using said molecular marker for identifying germplasm associated with aphid resistance in said progeny soybean plant.
