QTL mapping of seed protein and oil traits in two recombinant inbred line soybean populations

Seed oil and seed protein contents are commercially important components of soybean (Glycine max (L.) Merr.) that inversely correlated. The objectives this study were to identify novel quantitative trait loci (QTL) validate existing QTL associated with oil, protein, weight in soybean. Two mapping populations, Pop 201 202, consisting 180 170 recombinant inbred lines (RILs), respectively, used study. phenotypic data for each population collected from four environments. linkage maps 202 consisted 421 416 polymorphic single nucleotide polymorphism (SNP) markers, respectively. Multiple Mapping (MQM) analyses identified a total 13 7 6 (SDWT). content not co-located found on chromosomes 17 18 multiple environments These can be useful reducing the inverse correlation between contents. Most previously reported genomic regions, thus provide additional evidence stability those across genetic environmental backgrounds. findings insight into control these traits potentially enable breeders utilize QTL-linked SNPs marker-assisted selection (MAS).
