Summary

This three-part series of presentations is designed to aid agricultural professionals in all soybean production regions of the world in understanding variability among soybean cyst nematode populations (SCN) and among SCN-resistant soybean varieties. Part 1 explains and illustrates the use of the female index for identifying and classifying soybean resistance to SCN in greenhouse tests. After seeing this presentation, viewers will know how SCN resistance is measured and categorized. Part 2 explains and illustrates how to test SCN populations for their ability to overcome soybean resistance and how to use SCN type test results to manage SCN. Viewers will learn what a SCN type is and when they should have an SCN Type Test. Part 3 is intended for those who are interested in a more in-depth explanation of the relationships among SCN races, HG types, and SCN types. After seeing this presentation, viewers will understand the close similarity among all three measurements of SCN variability.​​
