GWAS of tiller number to identify TN1. (a) Manhattan plot of GWAS results. Red dots represent QTLs. (b) Regional Manhattan plot of qTN2 and pairwise LD analysis. Significant SNPs (−log₁₀(P) ≥ 4) are presented as red dots. Green and red boxes indicate annotated genes, triangles denote QTLs, and dots represent SNPs. (c) TN1‐based association mapping. Red dots indicate SNPs (−log₁₀(P) ≥ 4) in the 2000 bp promoter and 7467 bp genomic sequence. (d) Haplotypes (hap) of TN1 among 279 accessions; major and minor alleles are indicated in yellow and green respectively. Data are presented as mean ± SE. Different letters indicate significant differences at P < 0.05 according to two‐tailed Student's t‐test.
