Reproduction of Soybean Cyst Nematode on Dry Bean Cultivars Over Multiple Generations
Autor: Susilo H. Pormarto, Berlin D. Nelson, Theodore C. Helms
Publikováno v: Plant disease. 95(10)
Phaseolus vulgaris is a host of soybean cyst nematode (SCN; Heterodera glycines), a pathogen recently introduced into the major dry bean production area of North Dakota and northern Minnesota. The nematode reproduces less on most bean classes compare

Marker-assisted versus phenotypic selection for iron-deficiency chlorosis in soybean
Autor: C. M. Lamkey, R. J. Goos, Theodore C. Helms
Publikováno v: Euphytica. 194:67-78
Iron-deficiency chlorosis (IDC) is an important agronomic trait when soybean (Glycine max (L.) Merr.) is planted on calcareous soil. Breeders need confirmation that marker-QTL (quantitative trait loci) associations developed using association mapping

Single-seed descent, single-pod, and bulk sampling methods for soybean
Autor: Mizuki Funada, J. J. Hammond, Khwaja Hossain, Theodore C. Helms, Curt Doetkott
Publikováno v: Euphytica. 192:217-226
The single seed descent (SSD) method of inbreeding minimizes the amount of genetic sampling. The single-pod descent (SPD) and bulk methods (BM) produce redundant inbred lines that are descended from either the same F2 or F3 plant. However, for soybea

Impact of Rag1 Aphid Resistant Soybeans on Binodoxys communis (Hymenoptera: Braconidae), a Parasitoid of Soybean Aphid (Hemiptera: Aphididae)
Autor: Patrick B. Beauzay, Theodore C. Helms, Jason P. Harmon, Janet J. Knodel, Deirdre A. Prischmann-Voldseth, Kiran Ghising, Paul J. Ode
Publikováno v: Environmental Entomology. 41:282-288
Multiple strategies are being developed for pest management of the soybean aphid, Aphis glycines Matsumura; however, there has been little published research thus far to determine how such strategies may influence each other, thereby complicating the

Soybean Iron‐Deficiency Chlorosis Tolerance and Yield Decrease on Calcareous Soils
Autor: William T. Schapaugh, David W. Franzen, Alan J. Schlegel, R. J. Goos, R. A. Scott, Theodore C. Helms
Publikováno v: Agronomy Journal. 102:492-498
Cultivar selection is one of the best ways to manage iron-deficiency chlorosis (IDC) problems in soybean [Glycine max (L.) Merr.]. The objective was to determine if precision farming techniques of planting IDC-tolerant cultivars in calcareous soil ar

Soybean Tolerance to Water-Saturated Soil and Role of Resistance to Phytophthora sojae
Autor: Theodore C. Helms, B. J. Werk, Edward L. Deckard, B.D. Nelson
Publikováno v: Crop Science. 47:2295-2302
There are differences among soybean [Glycine max (L.) Merr.] genotypes for tolerance to water-saturated soil conditions. Phytophthora root rot caused by Phytophthora sojae (M.J. Kaufmann and J.W. Gerdemann) is problematic for soybean when the soil is
