Genetic Improvement

The science surrounding genetic improvement of soybean has the potential to impact all aspects of the value chain.  Genetic resistance to biotic and abiotic (or environmental) factors have a profound impact on production, crop values and profitability.

An expanded understanding of soybean gene function (with regards to genes controlling maturity, agronomic characteristics, nutrient uptake and partitioning) will make public and private soybean breeding more efficient and responsive to changing demands, by facilitating the selection of desirable genes in breeding populations. 




Dr. Karen Hudson received her PhD from the University of Maryland in 1997 and joined the research staff of USDA-ARS located in West Lafayette in 2007. Her research focus is on the molecular genetics of soybean seed development. She collaborates with several Purdue University faculty.



Dr. Jianxin Ma received his PhD from the Chinese Academy of Agricultural Sciences (CAAS) in 1999 and then joined the Purdue Department of Agronomy in 2005. His primary focus has been the development of new genomics tools for soybeans for germplasm enhancement.​​


Dr. Katy Martin Rainey received her PhD from Cornell University in 2005 and is an Assistant Professor in the Purdue University Department of Agronomy. She studies genetic improvement of soybeans for increased yield and better quality using multidisciplinary approaches including precision and high-throughput phenotyping. Dr. Rainey has been breeding soybeans for 10 years and has released specialty cultivars.
