Identification of Genomic Region Governing Yield Related Characters in Soybean, Glycine max (L.) Merrill Using SNP Markers

The present study was carried out to identify the quantitative trait locus (QTL) associated with seed yield related characters in soybean using F2 population. A population of 63 F2 plants were genotyped by 32 SNP markers. Nine QTLs were found to be associated with seed yield related characters (3 QTLs for days to flowering (DTF), 3 QTLs for days to maturity (DTM), 2 QTLs for total pod weight (TPW) and 1 QTL for seed yield (SYP)) and were found located on the linkage group A1 (chromosome 5). The QTLs for DTF and DTM identified in this study could be regarded as stable QTLs because of their detection in the two years. However, two novel QTLs for days to flowering (DTF) and total pod weight (TPW) on linkage group A1 were identified in the present study.
