Overwinter Population Dynamics of Heterodera glycines.

Journal of nematology, 2011
The purpose of this research was to compare the overwinter survival of populations of Heterodera glycines at different latitudes in the United States and the effect of changing latitudes before and after the initiation of dormancy. Soil samples infested with H.

Tolerance of Soybean to Heterodera glycines.

Journal of nematology, 2011
Seven soybeans were selected from 200 entries evaluated for tolerance to soybean cyst nematode (SCN), Heterodera glycines. Tolerance to SCN was measured by comparing the seed yield from aldicarb-treated vs. nontreated plots. A yield response index (YRI) was calculated for each entry: YRI = (seed yield from nontreated plot/seed yield from treated plot ...

Dormancy of Heterodera glycines in Missouri.

Journal of nematology, 2011
A 2-year study was conducted in field microplots to determine the relative importance of soybean phenology and soil temperature on induction of dormancy in Heterodera glycines in Missouri. Four near-isogenic soybean lines differing for maturity date were planted in microplots infested with a race 5 isolate of H. glycines. Soil temperature was monitored

Resistance of Soybean Cultivars to Heterodera glycines HG type 2.5 in Korea

Research in Plant Disease, 2013
A total of 75 soybean cultivars developed in Korea was screened against soybean cyst nematode (SCN), Heterodera glycines HG type 2.5. Cysts developed on soybean cultivars ranged from 104 to 624 cysts per pot.

Tolerance to Heterodera glycines in Soybean.

Journal of nematology, 2011
Fifty-four susceptible soybean, Glycine max, cultivars or plant introductions were evaluated for tolerance to H. glycines, the soybean cyst nematode (SCN). Seed yields of genotypes were compared in nematicide-treated (1,2-dibromo-3-chloropropane, 58 kg a.i./ha) and nontreated plots at two SCN-infested locations over 3 years.

Novel global effector mining from the transcriptome of early life stages of the soybean cyst nematode Heterodera glycines

Scientific Reports, 2018
Soybean cyst nematode (SCN) Heterodera glycines is an obligate parasite that relies on the secretion of effector proteins to manipulate host cellular processes that favor the formation of a feeding site within host roots to ensure its survival.

Distribution of Heterodera glycines in Ohio.

Journal of nematology, 2011
A 4-year systematic survey for the presence of soybean cyst nematode Heterodera glycines in Ohio soybean fields was initiated in 1992. A total of 667 soybean fields in 63 counties was sampled. Heterodera glycines was present in 91 fields in 40 counties based on soil samples collected, and in one field in each of three additional counties based on soil ...

Caracterização molecular de populações do nematóide-de-cisto-da-soja com diferentes índices de parasitismo na cultivar Hartwig Molecular characterization of soybean cyst nematode populations with different parasitism index to the Hartwig cultivar

Pesquisa Agropecuária Brasileira, 2001
Recentemente, foi descoberta uma raça do nematóide-de-cisto-da-soja (NCS; Heterodera glycines) que apresentou a capacidade de quebrar a resistência da cultivar Hartwig, até então considerada resistente a todas as raças conhecidas do nematóide.

Selection and Inbreeding of Heterodera glycines on Glycine max.

Journal of nematology, 2011
Few soybean cyst nematodes (SCN), Heterodera glycines, of a diverse gene pool developed into females on soybeans PI 89772 or PI 209332. Nematodes surviving the selection pressure were then inbred for nine generations by single cyst transfers on the same selecting soybean line.
