Wendy Hoashi-Erhardt researches traits of interest in strawberry and raspberry genotypes with the Small Fruit Breeding Program. Additionally, she spearheads the plant breeding of day-neutral strawberries for production in the Pacific Northwest. Wendy has a M.S. in crop science from Cornell University and a B.S. in chemistry from Wheaton College (IL). In the last 10 years, she has collaborated in the release of three cultivars of raspberry and strawberry.

Areas of Interest

  • Breeding and evaluating day-neutral strawberries for fresh market use
  • Evaluating strawberries for processing and fresh market uses
  • Evaluating raspberries compatible with machine harvesting and processing
  • Studies on Raspberry Bushy Dwarf Virus, phytophthora root rot, and verticillium on raspberries
  • Organic berry production
