Fig. 3: Higher numbers of reduced-susceptibility haplotypes across QTLs associated with lower susceptibility to fire blight.

From: Fire blight QTL analysis in a multi-family apple population identifies a reduced-susceptibility allele in ‘Honeycrisp’

Fig. 3

Distributions, means, and 95% confidence intervals of adjusted shoot length blight best linear unbiased predictions (SLB BLUPs) across years for 314 apple offspring with increased-susceptibility haplotypes present and absent grouped by a number of reduced-susceptibility haplotypes at a combination of three QTLs on chromosomes 6, 7, and 15. Offspring with haplotype 6R, 7B, 7T, and/or 15A were considered to have increased-susceptibility haplotypes present; reduced-susceptibility haplotypes were 6E, 6N, 6O, 7P, 15J, and 15L (corresponding with designations in Fig. 1). Offspring with neutral-effect haplotypes (i.e., haplotypes exhibiting non-significant effects in 2016 and/or 2017) at all three QTLs were considered to have no increased- and reduced-susceptibility haplotypes (gray bar). Different mean separation letters represent the least significant differences with a Bonferroni p adjustment (α < 0.05)
