Heterodera

have been exploited from different soybean germplasm for developing resistant soybean cultivar against Heterodera glycines (Concibido et al., 2004b). The resistance genes to Heterodera glycinces were explored first time in soybean germplasm Peking, which conferred three recessive genes rhg1, rhg2, and rhg3 in 1960(Caldwell et al., 1960) later the fourth new dominant gene Rhg4 resistant to Heterodera glycinces was also identified in Peking, which was closely linked to i locus and responsible for distribution

Soybean cyst management tactics include different method from place to place, but all have the common method of using resistant soybean cultivar and crop rotation and these are found to be more effective than others.(Niblack et al., 2003, Schmitt et al., 2004). Lotus japonicus is one of the important model leguminous plant to study the interaction and compatibility of plant parasitic nematode to cause infection (Lohar & Bird, 2003). There are large number of resistant soybean cultivar to SCN and

Authorship: Behavioral differences of Heterodera glycines and Meloidogyne incognita infective juveniles exposed to root extracts in vitro, Masler et.al, Submitted. Efficiently conducted biochemical and biological assays, scheduled assigned experiments, and collected and prepared samples for analysis. In select research projects was involved in literature searches, experiment design and performance, and data analysis. Regularly sought and developed improvements to protocols; discussed possible implementation

Effects of Crop Rotation of Soybean with Corn on Severity of Sudden Death Syndrome and Population Densities of Heterodera Glycines in Naturally Infested Soil; there was 2.4 million tonnes of soybean loss in 2005 due to SDS (One tonnes is equivalent to 1.1 U.S. tons.). Sudden Death Syndrome is caused by two main pathogens, the fungus, Fusarium virguliforme, and the soybean cyst nematode, Heterodera glycines. Sometimes symptoms are confined to certain strips in the field. This may be due to soil structure

Exotic soybean germplasm that has the potential to significantly increase seed yield has been evaluated in several previous studies. Three high yielding germplasm lines that contain exotic ancestry have been released by USDA-ARS and the Illinois Agricultural Experiment Station. The released lines LG00-3372 from the cross PI 561319A × PI 574477 (Nelson and Johnson 2011a), LG04-6000 from the cross PI 436682 × Lawrence (Nelson and Johnson 2012), and LG06-5798 from LG00-3372 x LD00-3309 (Nelson et al
