1. A method of identifying a soybean plant that comprises a genotype associated with an aphid resistance phenotype, comprising:
i) detecting in said soybean plant an allele in at least one aphid resistance marker locus associated with the aphid resistance phenotype wherein the aphid resistance marker locus is in a linkage group J genomic region flanked by: a) loci NGMAX007665986 and NGMAX007668908; b) loci NGMAX007666844 and loci NGMAX007668908; c) loci NGMAX008369613 and loci NGMAX007668908; d) loci NGMAX007667203 and loci NGMAX007668908; e) loci NGMAX007667293 and NGMAX007668908; f) loci NGMAX007667294 and NGMAX007668908; g) loci NGMAX008369613 and NGMAX007668495; h) loci NGMAX007667203 and NGMAX007668495; i) loci NGMAX007667293 and NGMAX007668495; j) loci NGMAX007667294 and NGMAX007668495; k) loci NGMAX008369613 and NGMAX007668492; l) loci NGMAX007667203 and NGMAX007668492; m) loci NGMAX007667293 and NGMAX007668492; or, n) loci NGMAX007667294 and NGMAX007668492; and, ii) denoting that said plant comprises a genotype associated with an aphid resistance phenotype.
