Field to Film: Featured Research | Dr. Chen Talks Soybean Breeding in Arkansas

Breeding Soybean Cultivars with High Yield Potential, Improved Seed Quality Traits, and Multiple Disease Resistance and Pre-foundation Seed Production Investigator(s): Dr. Pengyin Chen, UA Division of Agriculture Soybean Breeder, and colleagues: David Moseley, Tina Hart, Max Wyss, Jody Hedge, Bill Apple, Jonathan McCoy, and Scott Hayes Stated Goal: To provide a steady flow of new and improved soybean cultivars (varieties) with high productivity and profitability to the soybean industry. Specific Objectives: 1. Develop high-yielding maturity group (MG) 4-6 varieties that include both Roundup Ready and non-GM lines that are adapted to various environments and production systems in Arkansas. 2. Develop new varieties and germplasm that have resistance to soybean cyst nematode (SCN), root knot nematode (RKN), sudden death syndrome (SDS), stem canker (SC), frogeye leaf spot (FLS), and soybean mosaic virus (SMV). Progress Report: Due to the growing interest among soybean growers for conventional (non-GM) varieties, the soybean breeding program of the University of Arkansas has, for decades, released high-yielding conventional (Non-GM) public varieties. In 2013, foundation seeds of 2 new determinate maturity group 5 high yielding conventional cultivars, UA5213 C (880 units) and UA 4913 C (121 units) were produced. Both of these varieties are competitive with commercial MG late 4 and early 5 cultivars available in southern states. In addition, the Arkansas Foundation Seed program produced Foundation Grade seed of Osage, Ozark, UA 5612 (released in 2012), and Hutcheson with 848, 783, 552, and 419 units, respectively.
