Registration of Soybean Germplasm Line DB04-10836 with High Yield Potential and Resistance to Soybean Cyst Nematode

New soybean [Glycine max (L.) Merr.] lines with high yield potential are needed by public and private soybean breeders. Soybean germplasm line DB04-10836 (Reg. No. GP-398, PI 674010), a late maturity group V (relative maturity 5.8) line, was developed by the USDA-ARS, Stoneville, MS. It is a conventional germplasm line with high yield potential and resistance to soybean cyst nematode (SCN) (Heterodera glycines Ichinohe Race 3) populations, moderate resistance to southern root-knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood], and resistance to southern stem canker [caused by Diaporthe phaseolorum (Cooke & Ellis) Sacc. var. meridionalis F. A. Fernondez]. DB04-10836 was derived from the cross DT99-16788 x J00-2. The plant population was advanced from the F-2 to F-3 by the single-pod bulk method and then advanced to the F-5 generations by bulk increase. DB04-10836 is derived from a single-plant selection from the F-5 population. It was tested in multiple environments in USDA-ARS tests in Mississippi, the Uniform Soybean Tests-Southern States, and the Mississippi Soybean Variety Trials. In the Uniform Tests over 64 trials at 23 locations from 2009 to 2011, DB04-10836 ranked highest for yield, was significantly higher yielding than both check cultivars 'Osage' and '5002T' at Pine Tree, AR, and was significantly higher yielding than 5002T at Suffolk, VA. Neither of these checks are resistant to SCN Race 3; therefore, DB04-10836 will be useful as a high-yielding SCN resistant parent for cultivar development.
