“…For SCN resistance, the cultivar Hartwig was utilized as a resistance source in different soybean breeding programs to develop superior soybean cultivar with broad resistance to SCN (Anand 1992;Faghihi et al 1995). Vierling et al (1996) identified and mapped a QTL region on Chromosome (Chr.…”

Out of these accessions, 64 PIs were identified with high or moderate resistance to RKN. Of these 64 lines, 24 accessions showed good resistance to both RKN and RN. These new sources of resistance to multiple nematodes will be valuable materials for soybean breeding programs to develop new resistant cultivars that can overcome yield losses caused by one or more of these nematode species.

“…However, the SDS resistance of Hartwig was partial and could be defeated by heavy fungal infestations . Hartwig was strongly resistant to most HG Types of SCN (Anand 1992;Niblack et al 2003). Flyer was susceptible to most SCN HG Types and partially susceptible to SDS (McBlain et al 1990;Gibson et al 1994;Njiti et al 1997;Yuan et al 2002;Kazi 2005).…”

“…Hartwig at advanced inflection stages in our study were characterized by cellular necrosis and secondary cell wall thickenings, which resembled those found in SCN-resistant soybean PI 437654, the original genetic source of cv. Hartwig (Anand, 1992;Anand et al, 1985;Kim et al 2010). The infecting nematodes are likely doomed to death due to the degeneration of the syncytia they feed on.…”

Initial subcellular responses in susceptible (PI 274420) and resistant (cv. Hartwig) soybeans infected with the soybean cyst nematode (SCN) were examined 2 and 4 days after inoculation (DAI). Subcellular features common to both soybeans at 2 DAI included hypertrophied initial syncytial cells (ISCs) and syncytium-component cells (SCs) with a dense cytoplasm containing proliferated rough and smooth endoplasmic reticulum (RER and SER), a hypertrophied nucleolus, and reduced vacuoles, suggesting that the nematode-infected cells were dedifferentiated. In the resistant soybean, a striking initial subcellular difference from the susceptible soybean was the dilation of the RER, indicating ER dysfunction and leading to cell death. This disturbed nematode feeding, as evidenced by disrupted feeding tubes. In PI 274420, the ISC cytoplasm was depleted, with the exception of ER membranes, at 4 DAI, while the SC cytoplasm was dense with proliferation of starch-containing plastids around multiple nuclei that might be derived from the congregation of nuclei in the neighboring SCs and in part by nuclear division without cytokinesis. In cv. Hartwig, syncytia were necrotized with secondary cell wall thickening outside the plasma membrane and an extremely dense cytoplasm containing a nucleus with an electron-lucent nucleolus, accompanied by the proliferation of closely stacked parallel RER and ribosomes. These results suggest that syncytia develop continuously in PI 274420 to produce and store nutritional substances in SCs, providing for the nematode through ISC until maturation, but in cv. Hartwig, syncytia degenerate early due to excessive metabolism, blocking nematode feeding and cytoplasmic connections with adjacent intact cells.
