“…Some studies indicate that insect resistance is quantitatively inherited (Sharma , Jun et al. ). Therefore, selection for soybean cultivars with high resistance against SPB requires the evaluation of resistance in multiple environments over several years.…”

Soybean pod borer (SPB) (Leguminivora glycinivorella (Mats.) Obraztsov) causes severe loss of soybean (Glycine max L. Merr.) seed yield and quality in some regions of the world, especially in north-eastern China, Japan and Russia. Isoflavones in soybean seed play a crucial role in plant resistance to diseases and pests. The aim of this study was to find whether SPB resistance QTL are associated with soybean seed isoflavone content. A cross was made between 'Zhongdou 27' (higher isoflavone content) and 'Jiunong 20' (lower isoflavone content). One hundred and twelve F 5:10 recombinant inbred lines were derived through single-seed descent. A plastic-net cabinet was used to cover the plants in early August, and thirty SPB moths per square metre were put in to infest the soybean green pods. The results indicated that the percentage of seeds damaged by SPB was positively correlated with glycitein content (GC), whereas it was negatively correlated with genistein (GT), daidzein (DZ) and total isoflavone content (TI). Four QTL underlying SPB damage to seeds were identified and the phenotypic variation for SPB resistance explained by the four QTL ranged from 2% to 14% on chromosomes Gm7, 10, 13 and 17. Moreover, eleven QTL underlying isoflavone content were identified, and ten of them were encompassed within the same four marker intervals as the SPB QTL (BARC-Satt208-Sat292, Satt144-Sat074, Satt540-Sat244 and Satt345-Satt592). These QTL could be useful in marker-assisted selection for breeding soybean cultivars with both SPB resistance and high seed isoflavone content.

“…Primer design using the peanut reference genome was conducted by Primer3 (v2.3.5) (Untergrasser et al 2012). Validation of developed makers was performed by the PCR protocol described by Jun et al (2013). CAPS marker analysis for each PCR product was conducted by treatment of four restriction enzymes including AseI, MseI, MspI, and PstI, respectively.…”

ABSTRACT The objective of this study was to develop high-throughput SNP or SNP-based markers by re-sequencing of two peanut cultivars, 'K-Ol' and 'Pungan'. The whole genome re-sequencing for the two cultivars was performed to produce sequences of 35.3 × 10 9 bp with 350 × 10 6 reads and 32.0 × 10 9 bp with 318 × 10 6 reads, respectively. As compared with the peanut reference genome, the distribution of homozygous and heterozygous SNPs on each chromosome showed very similar patterns between 'K-Ol' and 'Pungan', and most of them were in intergenic-region regardless of the peanut cultivars and reference genome type. The SNPs identified between the two peanut cultivars were evenly distributed across chromosomes of peanut diploid A and B reference genomes. It indicated that these SNPs could be available to construct a genetic map using the segregating population derived from a cross between 'K-Ol' and 'Pungan'. Total 61 CAPS marker were developed and tested for their availability. Of the CAPS markers, 60 CAPS markers produced normal PCR products and 18 out of them presented polymorphism among 6 peanut varieties. Results of the present study could provide useful genetic resources to facilitate marker-assisted selection for breeding programs as well as germplasm screening for peanut.

“…Host-plant resistance (HPR) is an important component of soybean aphid IPM. Currently, five soybean genes have been reported to provide some level of resistance to soybean aphids (Hill et al 2006a,b;Zhang et al 2010;Jun et al 2013). Named Rag genes (Resistance to A. glycines), these genes negatively affect soybean aphid biology (antibiosis) and under certain circumstances (e.g., genotype and gene type), may affect the insect's host preference (antixenosis).…”

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is an invasive species from Asia that has been the major economic insect pest of soybeans, Glycine max (L.) Merrill, since 2000. While use of soybeans expressing antibiosis and antixenosis is a well-studied strategy to manage this pest, aphid-tolerant soybeans remain underexplored. This study examined the relationship between cumulative aphid-days (CAD) and yield loss in the tolerant soybean KS4202 during two growing seasons to determine the economic injury levels (EILs) for soybean aphids on KS4202. Soybean aphid infestations were initiated during the soybean reproductive stages. A range of CAD treatments (3,000-45,000 CADs) were applied during the growing seasons. Aphid populations reached 45,000 CAD in 2011 and 38,000 CAD in 2013 in plots that were not treated with insecticides. It was estimated that the population doubling time was 9.4 d. In infested plots, soybean yield was reduced by 1.4-13.3%, equivalent to a 3.1% yield loss for every 10,000 CAD. Overall, most CAD treatments did not affect yield parameters, although CAD > 39,000 caused a significant reduction in most yield parameters. The EILs calculated for KS4202 ranged from 526 to 2,050 aphids/plant, which were approximately 2.5-fold higher when compared to EILs previously calculated for susceptible soybean. The adoption of soybean aphid tolerant soybean with higher EILs may help mitigate treatment delay problems by lengthening the treatment lead-time and possibly reduce the number of insecticide applications.
