Journal of Plant Registrations, Vol. 2, No. 1, January 2008 21 S oybean cultivar Dennison [Glycine max (L.) Merr.] (Reg. No. CV-493, PI 647087) was developed by the Ohio Agricultural Research and Development Center of The Ohio State University (OARDC-OSU). It was released on 1 August 2006 because of its high seed yield in Ohio and its resistance to Phytophthora root and stem rot [caused by Phytophthora sojae (M. J. Kaufmann and J. W. Gerdemann)]. The name was chosen to recognize the late David T. Dennison, who served as manager of the Ohio State University Agronomy Farm and as chief inspector for the Ohio Seed Improvement Association. The cultivar Dennison (previously designated HS1-3717) derived from an F 4 plant of the cross ‘Athow’ (Wilcox and Abney, 1997) × HS94-4533. The parent line HS94-4533 is from the same F 2 plant as ‘Kottman’ (St. Martin et al., 2001). The cross was made in the summer of 1997 at Columbus, OH, and subsequent development was by early generation testing. The F 2 -derived progenitor line, HS99-5217, was tested in Ohio from 1999 to 2001. The F 4:5 selection designated HS1-3717 was tested in multiple Ohio locations from 2002 to 2006. It was also tested regionally in the USDA Uniform Preliminary Test III in 2004 (Abney and Crochet, 2004). The cultivar has indeterminate stem habit, white fl owers, light tawny pubescence, tan pods, and yellow seeds with a black hilum. It is classifi ed in maturity group III (relative maturity 3.5), and is adapted as a full-season cultivar from 40 to 42° N lat. In Ohio tests (2003 to 2005, four or fi ve locations per year), mean seed yield of Dennison was 4553 kg/ha, compared with 4358 kg/ ha for Kottman, the most widely grown public cultivar in Ohio.
