Fig 5. Manhattan plots of the genome-wide association study for fruit weight.

Chromosome coordinates are displayed along the X axis with the–log₁₀ of the association P value for each single nucleotide polymorphism displayed on the Y axis. A greater–log₁₀ indicates stronger association with the trait. The green line denotes the significance threshold. The threshold for–log₁₀(P) was 6.0. Blue thick horizontal bars denote QTL positions reported previously, while brown horizontal thick bars are our results.
