Graph of Euclidean distance-based association values between SNPs on each chromosome.
The x-axis represents the 12 pepper chromosomes, and the y-axis represents the association value based on Euclidean distance. The colored dots represent the association values based on Euclidean distance at each SNP location. The red dashed line and black line represent association threshold and Loess-fitted values, respectively. Higher association values based on Euclidean distance indicate stronger association between a SNP and first flower node (FFN).

Graphs of the SNP-index of the H-pool (A), the L-pool (B), and the ΔSNP-index values (C) for association analysis.
The x-axis and y-axis indicate the 12 pepper chromosomes and the SNP index, separately. The black line represents the fitted SNP-index or ΔSNP-index. The red, blue, or green line indicates the threshold for association with FFN at the 99%, 95%, or 90% confidence interval, respectively.
