On the Influence of Susceptible and Resistant Soybean Varieties to the Development of the Soybean Cyst Nematode, Heterodera glycines (Heteroderidae, Nematoda)

Influence of susceptible and resistant soybean varieties to the development of the soybean cyst nematode(Heterodera glycines) was examined. It does not seem likly that there are any differences between varieties in attracting the Second Stage larvae of the nematode. In susceptible varieties, there were large populations and three generations during a ten·week examination period, while the resistant varieties maintained very low populations and had only two generations.
