    New publication shares insights into AI for crop improvement from Iowa State researchers

    For crop improvement, artifical intelligence provides a new lens to bridge science and practice, according to Jianming Yu, one of the world’s top-ranked scientists in the fields of quantitative genetics and plant breeding.

    “People have a lot of questions about how to actively start using AI in crop improvement. However, it is not easy to know how its tools can best be used,” said Yu, the Pioneer Distinguished Chair in Maize Breeding and director of the Raymond F. Baker Center for Plant Breeding in Iowa State University’s Department of Agronomy. 

    To help his peers, students and the public become more knowledgeable about the rapidly evolving field of AI, Yu and other co-authors, including Karlene Negus, a genetics doctoral student working with him, have published an overview on the role of AI in crop improvement in a scholarly compilation, Advances in Agronomy.
