Registration of G07-6012 and G07-6029 Soybean Germplasm, Which Derive 50% Pedigree from Wild Soybean

摘要

Two soybean [Glycine max (L.) Merr.] germplasm lines, G0-76012 (Reg. No. GP-394, PI 672992) and G07-6029 (Reg. No. GP-395, PI 672993), were developed and released by the University of Georgia Agricultural Experiment Stations. Both G07-6012 and G07-6029 are F-4-derived lines from the hybridization of 'N7103' x PI 366122, a wild soybean (G. soja Siebold & Zucc.) accession from Japan. G07-6029 is an early maturity group VII line, which yielded 2253 kg ha(-1), or 88% of the yield of its elite parent N7103, and 78 and 84% of the yield from cultivars NC-Roy and AGS 758 RR, respectively, over 15 replicated trials in the southern United States. G07-6012 is a late maturity group VII line, which yielded 88% as much as N7103 and 70, 76, 80, and 82% as the check cultivars 'N7002', 'Woodruff', 'NC-Raleigh', and 'N8001', respectively, in these same trials. Both G07-6029 and G07-6012 have seed quality and shattering and lodging resistance scores similar to those of the check cultivars. Both G07-6012 and G07-6029 have smaller seed than their G. max parent, N7103 (6.5 g 100-seed weight for G07-6029 and 5.0 g 100-seed weight for G07-6012 compared with 8.0 g 100-seed weight for N7013). These two germplasm releases are the first in the southern United States that were derived from a single cross involving wild soybean. Because of their diverse pedigree (50% from G. soja) and positive agronomic performance, G07-6012 and G07-6029 are released as valuable genetic resources for applied soybean breeding programs.
