“Global Dependence Upon Corn Belt Dent Maize Germplasm: Challenges and Opportunities” with Dr. Stephen Smith, Affiliate Professor at Iowa State University
Plant breeders are constantly trying to find the best crosses to increase the traits farmers and consumers want. However, continually crossing the same varieties can decrease the genetic gene pool over time, making plants susceptible to certain pests, diseases, and other stressors. To help understand the depth of the gene pool and to better understand how reliant we are on certain crop varieties, Dr. Stephen Smith and his team attempted to survey which maize varieties are bred and used the most. On this episode, we dive deep to discover what his team turned up.
