Regional Assessment of Soybean Brown Stem Rot, Phytophthora sojae, and Heterodera glycines Using Area-Frame Sampling: Prevalence and Effects of Tillage.
ABSTRACT The prevalence of brown stem rot (caused by Phialophora gregata), Heterodera glycines, and Phytophthora sojae in the north central United States was investigated during the fall of 1995 andExpand

Association of RFLP markers with loci conferring broad-based resistance to the soybean cyst nematode (Heterodera glycines)
Soybean cyst nematode (SCN) is a major soybean yield-limiting pest. The present study was conducted to map broad-based SCN resistance loci from the cultivar ‘Hartwig’. Two-hundred F2∶3 lines derivedExpand

An Efficient New Device to Release Eggs From Heterodera glycines.
A new apparatus to release eggs from cysts of soybean cyst nematode (Heterodera glycines) is described and its efficiency evaluated. A rubber stopper was mounted on a bolt, and cysts were groundExpand

Phylogenetic Relationships of Globodera millefolii, G. artemisiae, and Cactodera salina Based on ITS Region of Ribosomal DNA.
Globodera millefolii and G. artemisiae are interesting because their type localities (Estonia and Russia, respectively) are geographically distant from those of the potato cyst nematodes and otherExpand

Population Development of Pratylenchus hexincisus in Eight Corn Inbreds.
Of eight corn inbreds tested in the greenhouse and field, three (H60, H95, and H84) supported lower populations of Pratylenchus hexincisus than other inbreds included in this study. No apparentExpand
