Soybean [Glycine max (L.) Merr.] germplasm lines LB18-49 (Reg. no. GP-448, PI 699118), LB18-52 (Reg. no. GP-456, PI 699119), LB18-57 (Reg. no. GP-455, PI 699120), LB18-58 (Reg. no. GP-454, PI 699487), LB18-65 (Reg. no. GP-453, PI 699488), LB18-67 (Reg. no. GP-452, PI 699489), and LB18-75 (Reg. no. GP-451, PI 699121) are large seeded, non-genetically modified organism soybean lines ranging in maturity from maturity group (MG) 00 through MG IV. Each line contains a single gene for resistance to soybean aphid or Phytophthora root and stem rot (PRSR). LB18-49 and LB18-58 have resistance to soybean aphid biotype 3 (Rag1) provided by LD06-16721. Soybean aphid resistance to biotype 2 (Rag2) was derived from LD08-12441 for LB18-65. LD08-12582 provided Rag2 resistance for LB18-52 and LB18-57. ‘Williams 82’ was the source of the PRSR resistance gene, Rps1k, for LB18-67 and LB18-75. Large-seeded cultivars ‘Tohya’ (MG 00), ‘BeSweet 2001’ (MG II), ‘Gardensoy 24’ (MG II), and ‘Gardensoy 41’ (MG IV) served as recurrent parents with pest-resistant donor lines to develop large-seeded, pest-resistant soybean lines in a range of maturity groups. The combined pest resistance and large seed size, in a range of maturities, will be valuable for breeders developing large-seeded pest-resistant cultivars.
