GPAT, the rate-limiting enzyme in triacylglycerol (TAG) synthesis, plays an important role in seed oil accumulation. In this study, two  AhGPAT9  genes were individually cloned from the A- and B- genomes of peanut, which shared a similarity of 95.65%, with 165 site differences. The overexpression of  AhGPAT9  or the knock-down of its gene expression increased or decreased the seed oil content, respectively. Allelic polymorphism analysis was conducted in 171 peanut germplasm, and 118 polymorphic sites in  AhGPAT9A  formed 64 haplotypes ( a1  to  a64 ), while 94 polymorphic sites in  AhGPAT9B  formed 75 haplotypes ( b1  to  b75 ). The haplotype analysis showed that  a5 ,  b57 ,  b30  and  b35  were elite haplotypes related to high oil content, whereas  a7 ,  a14 ,  a48 ,  b51  and  b54  were low oil content types. Additionally, haplotype combinations  a62 / b10 ,  a38 / b31  and  a43 / b36  were associated with high oil content, but  a9 / b42  was a low oil content haplotype combination. The results will provide valuable clues for breeding new lines with higher seed oil content using hybrid polymerization of high-oil alleles of  AhGPAT9A  and  AhGPAT9B  genes.
