Table 3.
SNP associated (-log10 P-value ≥ 4) with bean rust disease severity scored 12 days after infection, their position within bean chromosomes, allelic reference and variant for each SNP, the frequency and effect of the variant allele, and the amount of phenotypic variance explained by each SNP associated with DS transf (BLUEs) in the common bean collection. Results are shown for two association mappings after removal of the 16 accessions showing mixed reactions: one with all the remaining accessions except the six considered incomplete hypersensitive resistant (to identify genes controlling partial resistance), and the other with all the remaining accessions except the 20 partially resistant (to detect genes controlling for incomplete hypersensitive resistance). All 11 associations were significant according to the Benjamini-Yekutieli (BY) FDR test

aIf the effect is positive, an increase in susceptibility is expected, whereas if the effect is negative it is expected an increase in resistance to bean rust
bAmount of the variance explained by each association, VQTL = 2freq(1-freq)effect2 and Vpheno = phenotypic variance of the DS transf (BLUEs)
