Genome-wide association for mapping QTLs linked to protein and oil contents in soybean

Abstract: -The objective of this work was to identify single-nucleotide polymorphism (SNP) markers linked with quantitative trait loci (QTLs) associated with increased contents of protein and oil in soybean. A total of 169 Brazilian soybean varieties, genotyped with 6,000 SNP markers, were evaluated. Protein and oil contents were obtained with the near-infrared reflectance method. Correlation and multiple linear regression analyses were used to identify linkage disequilibrium between SNP markers and the QTLs associated … Show more

“…Since oil and protein contents in soybeans are negatively correlated [4,5], the selection for simultaneous genetic gains for the two traits is difficult to perform successfully. As one of the causes of genetic correlation is a genetic linkage, the identification of recombinants can contribute to the simultaneous gain of both traits.…”
