        abstract = {Multiparental genetic mapping populations such as nested-association mapping (NAM) havegreat potential for investigating quantitative traits and associated genomic regions leading torapid discovery of candidate genes and markers. To demonstrate the utility and power of thisapproach, two NAM populations, NAM\_Tifrunner and NAM\_Florida-07, were used for dissectinggenetic control of 100-pod weight (PW) and 100-seed weight (SW) in peanut. Two high-densitySNP-based genetic maps were constructed with 3341 loci and 2668 loci for NAM\_Tifrunner andNAM\_Florida-07, respectively. The quantitative trait locus (QTL) analysis identi?ed 12 and 8major effect QTLs for PW and SW, respectively, in NAM\_Tifrunner, and 13 and 11 major effectQTLs for PW and SW, respectively, in NAM\_Florida-07. Most of the QTLs associated with PW andSW were mapped on the chromosomes A05, A06, B05 and B06. A genomewide associationstudy (GWAS) analysis identi?ed 19 and 28 highly signi?cant SNP?trait associations (STAs) inNAM\_Tifrunner and 11 and 17 STAs in NAM\_Florida-07 for PW and SW, respectively. Thesesigni?cant STAs were co-localized, suggesting that PW and SW are co-regulated by severalcandidate genes identi?ed on chromosomes A05, A06, B05, and B06. This study demonstratesthe utility of NAM population for genetic dissection of complex traits and performing high-resolution trait mapping in peanut.}
