Bean pyralid (BP; Lamprosema indicata Fabricius) is one of the major leaf-feeding insects that affect soybean crops in central and southern China. Four recombinant inbred line populations (KY, WT, XG and SX) were tested during 2004–2006 in Nanjing, China, to identify quantitative trait loci (QTL) for resistance to BP on the basis of data for rolled leaflet(More)
Association mapping (AM) combined with linkage mapping (LM) was executed to identify molecular markers and QTL regions associated with aluminum (Al) tolerance using relative root elongation (RRE) in hydroponics as an indicator. A set of 188 soybean cultivars released in Yellow and Changjiang River Valleys and 184 recombinant inbred lines (RIL) derived from(More)
Determining mitochondrial genomes is important for elucidating vital activities of seed plants. Mitochondrial genomes are specific to each plant species because of their variable size, complex structures and patterns of gene losses and gains during evolution. This complexity has made research on the soybean mitochondrial genome difficult compared with its(More)
Common cutworm (CCW; Spodoptera litura Fabricius) is a major leaf-feeding pest in Asia. The focus of this study was to explore the genetic mechanism for resistance to CCW in terms of antibiosis and antixenosis through mapping QTL (Quantitative trait locus/loci) in soybean using two recombinant inbred line populations. Larva weight (LW) and pupa weight (PW)(More)
The MADS-box transcription factors play fundamental roles in reproductive developmental control. Although the roles of many plant MADS-box proteins have been extensively studied, there are almost no functional studies of them in soybean, an important protein and oil crop in the world. In addition, the MADS-box protein orthologs may have species-specific(More)
Chromosome segment substitution line (CSSL) population is potential in precisely detecting and pyramiding genes/QTL/segments due to the genetic background noise removed. To exploit and utilize the favorable wild alleles, a CSSL population with 151 lines (SojaCSSLP1) was generated using a wild soybean (Glycine soja Sieb. et Zucc.) N24852 as donor parent and(More)
"Breeding by Design" as a concept described by Peleman and van der Voort aims to bring together superior alleles for all genes of agronomic importance from potential genetic resources. This might be achievable through high-resolution allele detection based on precise QTL (quantitative trait locus/loci) mapping of potential parental resources. The present(More)
Phytophthora sojae is an oomycete soil-borne plant pathogen that causes the serious disease Phytophthora root rot in soybean, leading to great loss of soybean production every year. Understanding the genetic basis of this plant–pathogen interaction is important to improve soybean disease resistance. To discover genes or QTLs underlying naturally occurring(More)
Common cutworm (CCW) is one of the more serious leaf-feeding pests of soybean, causing significant yield losses in China. We have studied a sample (526 accessions) of the Chinese soybean germplasm population by association analysis using 233 polymorphic markers. Our aim was to detect quantitative trait loci (QTL) and corresponding alleles relating heritable(More)
Annual wild soybean (Glycine soja Sieb. and Zucc.), the wild progenitor of the cultivated soybean [Glycine max (L.) Merr.], is valuable for improving the later. The construction of a linkage map is crucial for studying the genetic differentiation between these species, but marker density is the main factor limiting the accuracy of such a map. Recent(More)
