Candidate gene association analysis and haplotype analysis of GRMZM2G141205. (A) Manhattan plot for CRN in different environments. (B) pair-wise linkage disequilibrium (LD) of variants in GRMZM2G141205. (C) Haplotypes of GRMZM2G141205 among natural variations in inbred lines. (D) Phenotypic differences between different haplotypes. Levene's test (P = 0.93) indicated that the variance is homogeneous, so one-way ANOVA was used for comparisons between different haplotypes. The protected LSD post hoc test (a = 0.05) was used for multiple comparison tests. Different letters indicated that significant difference between haplotypes were observed (P < 0.05)
