Effects of MeAHL17 and MeTIR1 allele combinations on trait variation. a Tajima’s D distribution surrounding MeAHL17 andMeTIR1 loci. b Linkage disequilibrium heat map surrounding MeAHL17 and MeTIR1 loci. Red lines indicate the candidate region. c Allele distribution of MeAHL17 at position 11,671,475 (Red letters) and MeTIR1 at position 11,843,579 (Black letters) on chromosome 2 in wild and cultivated cassavas. d, e Box plots of SR weight (d) and SR starch content (e) based on indicated allele combinations. The center line represents the median, box limits indicate the upper and lower quartiles, and whiskers denote the range of the data. Pairwise multiple comparisons (median test, adjusted P < 0.05) were used to identify significant differences shown with different letters and no significant differences shown with the same letter. f Comparison of frequency of CBB resistance based on the indicated allele combinations. The black and red letters in d, e, and f indicate the same as in c
