Identifying Soybean Protein QTL in Lines With Exotic Pedigree.

Soybean meal provides a high-protein feed ingredient that is used predominantly in poultry and swine production. The objectives of this research were to identify high protein QTL in a line derived from a high protein germplasm line with exotic pedigree and to study the interaction of high protein QTL from different exotic sources. A population was developed by crossing the germplasm lines G03-3385 x N06-10035. N06-10035 is a high protein selection from the cross ‘Young’ x ‘N6202’. The line G03-3385 is a high protein selection from the cross ‘Benning’ x Korean PI ‘Danbaekong’. The population was phenotyped for total protein and total oil content, and genotyped with SNP and SSR markers. Preliminary single marker analysis identified significant marker trait association in chromosomes 1, 3, 9, and 20 at a significance level of p< 0.01.
