Spatial Distribution of Soybean Cyst Nematode in Research Plots

Distribution of soybean cyst nematode in nebraska.

A survey of 552 soybean fields in 20 counties in Nebraska in 1986-88 revealed 35 fields infested with the soybean cyst nematode (SCN), Heterodera glycines. Identification was confirmed with a greenhouse bioassay, using 'Lee 74' soybean, and by the application of a DNA hybridization probe derived from SCN mitochondrial DNA. Most of the SCN-infested fields were located on the Missouri River flood...

Worldwide distribution of soybean-cyst nematode and its economic importance.

Soybean-cyst nematode (Heterodera glycines) was first reported from Japan in 1915. It has since been reported from Korea (1936), Manchuria (1938), the United States (USA) (1954), and Egypt (1968). It is of major concern to soybean producers only in Japan and the USA. Soybean was a major crop in the Orient by 1915 but it was grown very little elsewhere. Since that time its cultivation has spread...

Engineered Soybean Cyst Nematode Resistance

Survey of soybean cyst nematode races in tennessee.

Cordell soybean is a newly released cultivar resistant to Heterodera glycines (SCN) races 3 and 5. The hectarage infested with these races and with other races that can parasitize Cordell in Tennessee is not known. A survey of races in Tennessee soybean fields with sampling weighted by soybean hectarage on a county basis was conducted in 1988. The SCN race plus female development on Bedford and...
