Registration of G13‐6299 Soybean Germplasm Line with Diverse Pedigree

Abstract

The soybean [Glycine max (L.) Merr.] germplasm line G13‐6299 (Reg. No. GP‐415, PI 682087) was developed and released by the University of Georgia (UGA) Agricultural Experiment Stations. G13‐6299 is an F5–derived plant selection from G00‐3213 × LG04‐6000. G13‐6299 is a conventional maturity group (MG) VII line containing 19% exotic germplasm by pedigree. G13‐6299 is derived from a wide cross of southern germplasm, G00‐3213 (MG VII), by northern germplasm, LG04‐6000 (MG IV). The genetic basis of US soybean germplasm is narrow, a problem that is further exacerbated by breeding material being grouped into northern versus southern germplasm. G13‐6299 combines beneficial diversity from both northern and southern germplasm to produce a high‐yielding southern germplasm line with a uniquely diverse genetic background. G13‐6299 yielded 110 and 112% of two elite check cultivars across five environments in yield trials conducted by the UGA Soybean Breeding Program. G13‐6299 also yielded 102 to 107% of four elite check cultivars across nine environments in the United Soybean Board Diversity MG‐7 Test. G13‐6299 possesses resistance to soybean cyst nematode (race 3) (Heterodera glycines) and moderate resistance to southern root‐knot nematode (Meloidogyne incognita). The diversity, yield, and desirable agronomic characteristics of G13‐6299 make this line ideal for use as germplasm to develop superior yielding soybean cultivars in the United States with genetic diversity.
