  1. Since some of the QTLs had confusing nomenclature or no nomenclature assigned by authors, we generated a unique name for each QTL. In our nomenclature, the QTL starts with a code ‘q’ followed by a short code for the resistance trait. The next one or two digits before the hyphen represent the chromosome number. The numbers after the hyphen represent the chromosomal location (in Mb) of the starting coordinates of the QTL in MB with one decimal point. We have used the first decimal point without rounding the number so that it can look closer to the original QTL location. Our nomenclature is given in column 2. We have given QTL interval for most of the QTLs. Wherever the QTL interval is not available only marker position is given. AUDPC (Area under disease progression curve) values have been preferred over DS (disease severity) values wherever available
  2. Chr Chromosome number, LOD Score Logarithm of the odds, R2/PVE Phenotypic variance explained in percentage. ‘-’: Data not available
  3. aThe QTL position is based on trait-associated markers of the joint linkage association mapping based on combined three double haploid populations
