Soybean [ Glycine max (L.) Merr.] germplasm line K1639‐2 (Reg. No. GP‐365, PI 658491) was developed and released by the Kansas State University Agricultural Experiment Station, Manhattan, KS, as resistance to both soybean aphid (SBA) ( Aphis glycines Matsumura), and soybean cyst nematode (SCN) ( Heterodera glycines Ichinohe). K1639‐2 was developed by crossing R93‐174 × ‘Northrup King S59‐60’. The line was a reselection in the F 8 generation from a heterogeneous F 4 –derived line. K1639‐2 has a relative maturity of 5.2, purple flowers, gray pubescence, yellow seed coats, dark buff hila, tan pod walls, and determinate growth habit. K1639‐2 is resistant to SCN HG Type 7 (race 3) and moderately resistant to HG Type 1.2.3.5.6.7 (race 4), and resistant to soybean aphid (Illinois biotype). K1639‐2 may be useful for breeders and researchers interested in developing new germplasm with resistance to SBA and SCN.
