Project Description: Genetic research of seed protein and oil content in soybeans

Soybean seed is known as a good source for protein oil. Seed protein and oil contents in soybean are quantitatively inherited and negatively correlated with each other. Also, the interactions of genes, genotypes and environment can determine both traits in soybean. Using genome-wide association study (GWAS) via multi-trait mixed model (MTMM) and multi-locus mixed model (MLMM), we will identity single nucleotide polymorphism (SNP) markers controlling seed protein and oil contents in soybean.
