“…We were encouraged to read recently that Zhou et al. (2021) found that qSCN10 was not associated with any yield drag in their study. This opens up the possibility that lines derived from this source, or from JTN‐5316, JTN‐5416, or JTN‐5516, could yield at least as well as JTN‐5203 or other lines with only the Hartwig source of resistance.…”

PI 691526) were released by the USDA-ARS in 2019 and trace 25% of their pedigree to PI 567516C. These F 6 -derived sister lines are the first releases derived from this accession. The new lines were developed to provide broad genetic resistance to the predominant damaging pest of soybean in the United States, soybean cyst nematode (SCN; Heterodera glycines Ichinohe), by combining the novel genetic resistance of PI 567516C with the established resistance of 'Hartwig'. Development of these lines was characterized by intensive selection of F 3 plants based on agronomic characteristics and simple sequence repeat markers associated with SCN resistance quantitative trait loci (QTL) in PI 567516C and Hartwig. The new lines have inherited resistance alleles at five QTL: two originating from PI 567516C and three originating from Hartwig, across four chromosomes. The lines were evaluated for and exhibit varying levels of resistance to other economically important pathogens of soybean, including: reniform nematode (Rotylenchulus reniformis Linford & Oliveira), frogeye leaf spot (caused by Cercospora sojina Hara), and southern stem canker (caused by Diaporthe phaseolorum var. meridionalis F. A. Fernández). JTN-5316, JTN-5416, and JTN-5516 were field tested for multiple years in Jackson and Milan, TN, and produce moderate seed yield. These determinate maturity group (MG) V germplasm lines are excellent parent material for breeding programs with an interest in incorporating broad genetic resistance to SCN.

“…Recently, a new race (X12) was identified in China (Lian et al 2017), which could infect all the tested soybean sources and showed a stronger virulence than race 4 (which had previously been thought the most virulent among all the SCN races). A 2nd population of race X12 was identified in Hekou Town, Gujiao City, Shanxi Province, China (Lian et al 2021). The rapid and reliable molecular diagnosis based on PCR was developed for SCN identification.…”

Soybean cyst nematodes: a destructive threat to soybean production in China

et al. 2021

Soybean cyst nematode (SCN), Heterodera glycines, is one of the most important pests in soybean production worldwide. In China, 11 different races of SCN, including a newly identified race ‘X12’ with super-virulence, have been surveyed and found to be distributed in 22 provinces. Among them, races 1, 3 and 4 are dominant in the two principal soybean-producing areas, Northeast China and Huanghuaihai Valley, causing over 120 million dollars of annual yield loss. Rapid and reliable PCR-based approaches have been developed for the molecular diagnosis of SCN. High-throughput methods for the identification of soybean resistance against SCN are also developed with specific single nucleotide polymorphism markers by using Kompetitive Allele Specific PCR technology. Over 10,000 soybean germplasm sources were evaluated for their SCN resistance, and 28 SCN-resistant soybean accessions were selected to construct an applied core collection, which has been used for soybean breeding in China. Recently, the genome sequences of SCN and soybean are publically available, and two major SCN-resistant genes (rhg1 and Rhg4) have been identified in soybean, which greatly facilitate the researches on SCN virulence and soybean resistance, and also soybean resistance breeding against SCN. However, the management of SCN still faces many bottlenecks, for instance, the single resistance genes in soybean cultivars can be easily overcome by new SCN races; the identified resistance genes are inadequate to meet the practical breeding needs; and our understanding of the mechanisms of SCN virulence and soybean resistance to SCN are limited. SCN is a destructive threat to soybean production throughout the world including China. In this review, the major progress on soybean SCN is summarized, mainly focusing on the recent research progress in SCN, soybean resistance to SCN and integrated management of SCN in China, and aiming at a better understanding of the current SCN research status and prospects for future work.
