Soybean cyst nematode (SCN) is a destructive threat to soybean production. It’s of economic importance to develop a new SCN-resistant soybean cultivar with high yield and other good agronomic traits. In this study, a yellow-seed-coated and yellow-hilum-pigmented cultivar Heinong 531 belonging to maturity group I was developed by a pedigree breeding method through a testcross between a female parental SCN-resistant soybean cultivar Pengdou 158 and a male parental line F1 (high-yield but SCN-susceptible Hefeng 55 x SCN-resistant Kangxian 12). Heinong 531 was evaluated for SCN resistance in both SCN-infested field and autoclaved soil inoculated with hatched second-stage juveniles of SCN HG Type 0. The results indicated that SCN development at all stages in Heinong 531 was suppressed and the female index was only 1.6-5.6%. Heinong 531 as well as Pengdou 158 and Kangxian 12 were identified to carry the Peking-type resistance with both rhg1-a GmSNAP18 and Rhg4 GmSHMT08 genes. In the two-year regional trials, the average yield of Heinong 531 reached 2805.0 Kg/ha and the one-year production trial demonstrated an average yield of 2751.5 Kg/ha with yield increase of over 12.0% when compared to the local cultivars. The average seed-fat (oil) contents of Heinong 531 reached up to 22.3%. The Peking-type SCN-resistant Heilong 531 cultivar with enhanced yield and high seed-oil contents was just released in China in June, 2021 with certified number of ‘Heishendou 20210004’. These good agronomic traits make Heinong 531 prospective in a wide extension to control SCN in the main soybean-producing areas of Northeast China.

Abstract Background Domestication and improvement processes, accompanied by selections and adaptations, have generated genome-wide divergence and stratification in soybean populations. Simultaneously, soybean populations, which comprise diverse subpopulations, have developed their own adaptive characteristics enhancing fitness, resistance, agronomic traits, and morphological features. The genetic traits underlying these characteristics play a fundamental role in improving other soybean populations. Results This study focused on identifying the selection signatures and adaptive characteristics in soybean populations. A core set of 245 accessions (112 wild-type, 79 landrace, and 54 improvement soybeans) selected from 4,234 soybean accessions was re-sequenced. Their genomic architectures were examined according to the domestication and improvement, and accessions were then classified into 3 wild-type, 2 landrace, and 2 improvement subgroups based on various population analyses. Selection and gene set enrichment analyses revealed that the landrace subgroups have selection signals for soybean-cyst nematode HG type 0 and seed development with germination, and that the improvement subgroups have selection signals for plant development with viability and seed development with embryo development, respectively. The adaptive characteristic for soybean-cyst nematode was partially underpinned by multiple resistance accessions, and the characteristics related to seed development were supported by our phenotypic findings for seed weights. Furthermore, their adaptive characteristics were also confirmed as genome-based evidence, and unique genomic regions that exhibit distinct selection and selective sweep patterns were revealed for 13 candidate genes. Conclusions Although our findings require further biological validation, they provide valuable information about soybean breeding strategies and present new options for breeders seeking donor lines to improve soybean populations.

Spread of soybean cyst nematode Heterodera glycines (SCN) to much of the soybean (Glycine max) growing region in the Midwest has created a persistent and significant annual yield loss for soybean. Host resistance has been the primary means of reducing yield loss to SCN. It is not known how moderately resistant cultivars fit into the management of SCN. Moderately resistant cultivars can have high yield potential, but nematode reproduction is greater than on resistant cultivars. Moderate resistance is defined by a SCN female index (FI) of 10 to 29 in standardized tests, whereas cultivars with an FI < 10 are considered resistant. Two each of SCN-resistant, moderately resistant, and susceptible (FI > 60) cultivars were planted in the same plots for two soybean crops in annual rotation with corn. The SCN population was reduced 80 and 54% by resistant and moderately resistant cultivars, respectively, and increased 189% by the susceptible. Yields of the resistant and moderately resistant were 8.2 and 11.8 bu/acre better, respectively, than for the susceptible. All plots were planted to a susceptible cultivar in the final year of the study, and demonstrated there was a carry-over effect from previous cultivars. Following resistant and moderately resistant cultivars, yields of the susceptible were 6.6 and 4.3 bu/acre above following susceptible cultivars. This study showed that moderately resistant soybean cultivars can be an effective tool for improving profitability of soybean. Accepted for publication 9 April 2008. Published 18 June 2008.

AbstractSoybean cyst nematode (SCN, Heterodera glycine Ichinohe) is the most damaging soybean pest worldwide and management of SCN remains challenging. The current SCN resistant soybean cultivars, mainly developed from the cultivated soybean gene pool, are losing resistance due to SCN race shifts. The domestication process and modern breeding practices of soybean cultivars often involve strong selection for desired agronomic traits, and thus, decreased genetic variation in modern cultivars, which consequently resulted in limited sources of SCN resistance. Wild soybean (Glycine soja) is the wild ancestor of cultivated soybean (Glycine max) and it’s gene pool is indisputably more diverse than G. max. Our aim is to identify novel resistant genetic resources from wild soybean for the development of new SCN resistant cultivars. In this study, resistance response to HG type 2.5.7 (race 5) of SCN was investigated in a newly identified SCN resistant ecotype, NRS100. To understand the resistance mechanism in this ecotype, we compared RNA seq-based transcriptomes of NRS100 with two SCN-susceptible accessions of G. soja and G. max, as well as an extensively studied SCN resistant cultivar, Peking, under both control and nematode J2-treated conditions. The proposed mechanisms of resistance in NRS100 includes the suppression of the jasmonic acid (JA) signaling pathway in order to allow for salicylic acid (SA) signaling-activated resistance response and polyamine synthesis to promote structural integrity of root cell walls. Our study identifies a set of novel candidate genes and associated pathways involved in SCN resistance and the finding provides insight into the mechanism of SCN resistance in wild soybean, advancing the understanding of resistance and the use of wild soybean-sourced resistance for soybean improvement.
