a TL, tunnel length in cm; SD, stem damage in percentage; and KR, kernel resistance on a subjective visual scale of 1 to 9 in which 1 indicates completely damaged and 9 indicates no damage.
b The number before the underscore (_) indicates the chromosome number and the number after the underscore (_) indicates the physical position in bp within the chromosome.
c The letter before the diagonal (/) is the nucleotide more frequent ; and the letter after the diagonal the nucleotide less frequent.
d N° = number of inbred lines homozygous for a determined allelic variant. The number before the diagonal (/) represents the number of individuals with the mayor allele; and the number after the diagonal represents the number of individuals with the minor allele.
e The additive effect was calculated as half the difference between the mean of the homozygous for the minor and the mean of the homozygous for the major allele.
f R 2, proportion of the phenotypic variance explained by the SNP.
g RMIP, resample model inclusion probability.
h Based on SNPs from Illumina chip, the remaining locations without a superscript are based on SNPs obtained by GBS.
