A Revised Classification Scheme for Genetically Diverse Populations of Heterodera glycines.
TLDR
The HG Type scheme described herein avoids the implication of genetic uniformity or predictability in contrast to the way the race scheme has been used. Expand
Effects of Tillage, Cultivar, and Planting Date on Percentage of Soybean Leaves with Symptoms of Sudden Death Syndrome
TLDR
A 4-year experiment, 1991 to 1994, was conducted in a field where sudden death syndrome (SDS) had previously been observed and there were no significant correlations between the percentage of leaves with SDS and yield. Expand

TLDR
Since the last time a feature article appeared in Plant Disease about SCN, some changes have occurred in the thinking about this pathogen and in approaches to managing soybean in infested fields. Expand
A model plant pathogen from the kingdom Animalia: Heterodera glycines, the soybean cyst nematode.
The soybean cyst nematode, Heterodera glycines, adversely affects the production of soybean, Glycine max, in many areas of the world, particularly in the United States, where it is the mostExpand
A chorismate mutase from the soybean cyst nematode Heterodera glycines shows polymorphisms that correlate with virulence.
TLDR
It is hypothesized that the chorismate mutase (Hg-cm-1) is a virulence gene, some forms of which allow SCN to parasitize certain resistant soybean plants. Expand
Correlation of Female Indices From Virulence Assays on Inbred Lines and Field Populations of Heterodera glycines.
TLDR
To avoid further adaptation, rotation of cultivars with resistance from these groups should be carefully monitored, including those from the most promising source of resistance, PI 437654, such as CystX. Expand
Distribution, Density, and Diversity of Heterodera glycines in Missouri.
TLDR
The data show that Heterodera glycines is widespread in Missouri, that most infested fields have population densities above the action threshold, and that there is considerable genetic diversity among H. glycines field populations. Expand
Interactions Between the Soybean Cyst Nematode and Fusarium solani f. sp. glycines Based on Greenhouse Factorial Experiments.
TLDR
Although both pathogens reduced the growth of soybeans, H. glycines did not increase SDS foliar symptoms, and statistical interactions between the two pathogens were seldom significant. Expand
Soybean yield losses due to Heterodera glycines in Iowa
Natural field infestations of Heterodera glycines race 3 in Boone (central Iowa) and Hancock (north central) counties were used to investigate the effect of the nematode on soybean growth and seedExpand
Rhg1 alleles from soybean PI 437654 and PI 88788 respond differentially to isolates of Heterodera glycines in the greenhouse
TLDR
Results suggest that PI 437654 and PI 88788 each have a different functional SCN resistance allele at or close to rhg1, and these allelic differences have implications that breeders should consider before incorporation into cultivars. Expand
