This is a series of three presentations designed to aid agricultural professionals in any soybean-production region of the world in understanding variability among soybean cyst nematode populations (SCN) and among SCN-resistant soybean varieties. The first presentation, "Measuring Resistance," explains and illustrates the use of the Female Index for identifying and classifying soybean resistance to SCN in greenhouse tests. After viewing this presentation, you will know how SCN-resistance is measured and categorized. The second presentation, "SCN Types for Farmers," explains and illustrates how we test SCN populations for their ability to overcome soybean resistance, and how to use SCN Type Test results to manage SCN. After viewing this presentation, you will know what an SCN Type is and when you should have an SCN Type Test. The last presentation, "Races No More," 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 viewing this presentation, you will understand the close similarity among all three measurements of SCN variability.
