Brief Project Summary:
To determine the effect of new cultivars developed by Syngenta on SCN reproduction, researchers will conduct growth chamber experiments with SCN populations that can reproduce at some level in both Peking and PI88788. For the test, commercially available SCN-resistant soybean varieties and susceptible soybeans will be used for the comparison. The experiment will be done in a growth chamber in containers with a randomized complete block design and four replications. After 28-30 days of inoculation, SCN females will be extracted from the root and counted. Data will be assessed for the reduction in reproduction compared to the susceptible soybeans.

Information And Results
Project Summary

Soybean cyst nematode (SCN) is an important limiting factor of soybean yield in Michigan. For many years, plant resistance was very effective in controlling SCN. Unfortunately, SCN has started adapting and reproducing in resistant varieties because of continuous use. Evaluating new soybean varieties with new lines of resistance is very important in order to improve resistance management in protect yields.

Project Objectives

Syngenta has developed two soybean cultivars, Golden Harvest and NK, which may have resistance to SCN. To determine the effect of these cultivars on SCN reproduction, we will set up growth chamber experiments, with SCN populations (SCN Type 1.2) that can reproduce at some level in both Peking and PI88788 (commercially available SCN resistant varieties). Soybean cyst nematode population (SCN Type 1.2) will be cultured on susceptible soybean in the growth chamber. For the test, commercially available SCN resistant soybean varieties (Peking and PI88788) and susceptible soybeans will be used for the comparison. The experiment will be carried out in cone-tainers in a growth chamber in a randomized complete block design with four replications. Inoculation will be done with approximately 1000 eggs per cone-tainer 5 days after seeding. After 28-30 days of inoculation, SCN females will be extracted from the root and counted under the dissecting microscope. Data will be analyzed to assess the reduction in reproduction compared to the susceptible soybeans.

Benefit To Soybean Farmers

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
