1. Characterization of quantitative resistance against Phytophthora sojae in soybean

    Phytophthora root and stem (PRR) is caused by the soil-borne oomycete Phytophthora sojae.  It is the second-most yield limiting soybean disease in Ohio (Carl Bradley, 2016 Extension Pathologist Survey, personal communication) and causes over 30 million bushels in yield reductions annually nationwide (Koenning and Wrather, 2010).

  2. Breeding Ohio-adapted Soybean Cultivars

    Soybean research in the McHale lab is intended to contribute to the very applied goal of new cultivar development for the Ohio and North-Central growing regions. Breeding goals include resistance to pests and pathogens important in Ohio and the North-Central region, improved quality traits important in the specialty food-grade soybean market, and added value traits such as low-linolenic acid.
