Abstract
Soybean cyst nematode (SCN; Heterodera glycines), an obligate parasite of plants, is the most damaging pathogen of soybean, causing $469 to $818 million in soybean yield losses annually in the United States. However, there are no soybean cultivars available that are resistant to all SCN populations. Therefore, much research is being conducted to develop soybean cultivars resistant to SCN (Matthews et al., 2013; Matthews et al., 2014; Youssef et al., 2013). Here we describe the rearing and harvesting of SCN, as well as how SCN can be assayed by determining the Female Index.
