Nicholas Santantonio

Overview

I am the new lead of a team of research scientists, staff and students that comprise the small grains breeding program at Virginia Tech. My interests include the quantitative genetics of agronomic traits and the integration of genomic selection and high-throughput phenotyping into a working breeding program. 

Expertise

  • Plant Breeding and Quantitative Genetics

Education

  • PhD Plant Breeding and Genetics, Cornell University 2018
  • MS Plant and Environmental Sciences, New Mexico State University, 2013
  • BS Genetics, New Mexico State University, 2010

The small grains breeding program aims to produce superior wheat and barley varieties for eastern North America, while doing basic research into the genetics behind important traits.

Our research focuses on integrating the latest genotyping and phenotyping technologies to accelerate genetic improvement for new and changing environments. We employ quantitative genetics theory to optimize breeding procedures and reduce generation times. We are also currently investigating the genetic basis of plant growth and development that lead to improved grain yield and quality, as well as trait stability for broad adaptation. 

We uphold the legacy of Dr. Carl Griffey by continuing to identify, select and pyramid important disease resistance loci for leaf and stripe rust, powdery mildew, and fusarium head blight.
