Technical Abstract: 'Ohio FG2' soybean (Glycine max (L.) Merr.) (Reg. no. CV-345,PI584470) was developed by the Ohio Agricultural Research and Development Center of The Ohio State University (OARDC-OSU). It was released 1 Aug 1994 as a specialty cultivar for production of tofu and other soy foods. Ohio FG2 is an F4-derived line, originally designated HS90-3513, from the cross 'LS301' x HS84-5247(2). The cross was made in the summer 1987 at Columbus, OH. The parent line HS84-6247 derives from 'Zane'(3) x HW79149(5,6), Ohio FS2 was developed by early-generation testing. The F2- derived line, HS88-8318 was tested in Ohio from 1988 to 1990. Ohio FS2, which derived from an F4 plant of HS88-8318, was tested in multiple Ohio locations from 1991 to 1994(4) and, under the designation HS90-3513, in the Uniform Soybean Tests, Northern Region, Preliminary Test IIIA, in 1993(7). Ohio FG2 has purple flowers, grey pubescence, brown pods and dull yellow seedcoats with gray hila. It is a Maturity Group III (relative maturity 3.2) indeterminate cultivar and is generally adapted as a full-season cultivar from 41 deg to 43 deg N lat. In Ohio tests (1991-1994), seed yield of Ohio FG2 was 15 percent greater than Vinton 81(1), a widely grown food-grade cultivar. Ohio FG2 yielded 9 percent less than the grain-type cultivar Resnik (3). Compared with Vinton 81, Ohio FG2 had 25 mg/seed greater seed weight, but 10 g/kg lower seed protein content. Lodging resistance of Ohio FG2 was similar to that of Vinton 81. Seed of Ohio FG1 produced soy-milk with solids content similar to that of Vinton 81. Ohio FG2 has a gene, derived from PI 82263-2, for race-specific resistance (Races 1,3,4, and 25) of phytophthora rot (caused by Phytophthora sojae M.J. Kaufmann & J. S. Gerdemann).
