The soybean [Glycine max (L.) Merr.] germplasm line G01-PR16 (Reg No. GP-371, PI 659503) was developed and released by the Georgia agricultural experiment stations in October 2007. It was released for its combination of resistance to Asian soybean rust (ASR; caused by Phakopsora pachyrhizi Syd.), bacterial pustule [caused by Xanthomonas campestris pv. glycines (Nakano) Dye], and southern root-knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood], and for its earlier maturity and higher seed yield relative to 'Hyuuga' (the late-maturing, ASR-resistant parent of G01-PR16). Asian soybean rust has become a consistent late-season problem in the southeastern USA, requiring soybean growers to apply fungicides to limit yield loss. G01-PR16 was selected from a cross between 'Dillon' and Hyuuga made in the summer of 1998. The F2-F5 generations of this population were advanced by single-seed descent to the F6 generation. Seed from a single F6 plant was composited and designated G01-PR16. Agronomic evaluation and ASR screening occurred in the southern USA. G01-PR16 produced the red-brown, or resistance, reaction to ASR in field plots near Attapulgus, GA with naturally occurring populations of P. pachyrhizi and in greenhouse evaluations when challenged with P. pachyrhizi isolates collected across Georgia. Over seven yield trials in Georgia and Arkansas, G01-PR16 (relative maturity of 6.4) matured an average of 2 d earlier than Dillon and had 90% of the seed yield of Dillon and 122% that of Hyuuga. Like Hyuuga, G01-PR16 contains the Rpp?(Hyuuga) resistance gene.
