This group studies the role of crop-wild hybridization in the evolution of weeds in Argentina and the persistence of crops or wild-like traits in different environments (e.g. ruderal vs. agrestal). On the other hand, the growing global demand for food is a challenge under a climate change scenario, where drought and high temperature conditions are becoming more frequent, which threat grain production in different regions of the world. Thus, this group also explores the variability of wild populations (e.g. tolerance to drought and heat stresses) to obtain genetic resources for crop breeding.

Research lines

  • Evolution of crop-wild relations in the agroecosystem
  • Identification of valuable traits in wild populations for crop improvement
