Crotalaria ochroleuca Susceptibility to Heterodera glycines Races
Journal of Agricultural Science, 2019 The aim of the study is to assess Crotalaria ochroleuca susceptibility to six Heterodera glycines races. To this, C. ochroleuca seedlings and two soybean cultivars were transplanted and individually inoculated with nematode races 1, 2, 3, 5, 6 and 14. Plants were collected and assessed 30 and 60 days after inoculation. Crotalaria ochroleuca reduced the

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.

Distribution of Heterodera glycines Races in Illinois.
Journal of nematology, 2011 Because the race scheme for Heterodera glycines was expanded recently from 5 to 16 races, the occurrence and distribution of races in Illinois need clarification. Forty-four populations of H. glycines were collected from sites in 23 of the 88 infested counties.

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.

Pathogenicity of Fungi to Eggs of Heterodera glycines.
Journal of nematology, 2011 Twenty-one isolates of 18 fungal species were tested on water agar for their pathogenicity to eggs of Heterodera glycines. An egg-parasitic index (EPI) for each of these fungi was recorded on a scale from 0 to 10, and hatch of nematode eggs was determined after exposure to the fungi on water agar for 3 weeks at 24 C.

Influence of Metyrapone on Development of Heterodera glycines.
Journal of nematology, 2011 Metyrapone, an inhibitor of steroid synthesis, affected the survival and rate of development of Heterodera glycines. Metyrapone in aqueous tartaric acid solvent influenced sex ratios. The effect on sex ratios was mediated through the host, whereas the effect on survival was apparently effected directly.

Polyploidy in an Amphimictic Population of Heterodera glycines.
Journal of nematology, 2011 A tetraploid single-cyst isolate of Heterodera glycines from a field population from Indiana has been propagated in the greenhouse on Lee soybeans since its discovery, in 1973. The tetraploid isolate has n = 18 chromosomes, compared with n = 9 of the diploid H.
