  1. REC indicates relative electrical conductivity, CC indicates chlorophyll content, Fv/Fm indicates maximum photochemical quantum efficiency
  2. The consistent QTLs qCC-1-5 and qREC-1-3 on chromosome 1 are shown in bold
  3. athe QTLs for REC, CC and Fv/Fm are temporarily named ‘qREC, qCC and qFv/Fm + number of chromosome + number of QTL’
  4. bThe position of heat tolerance-related QTLs
  5. cFlanking markers of heat tolerance-related QTLs
  6. dThe physical position of flanking markers linked with heat tolerance QTLs
  7. ePeak LOD value of the QTL
  8. fThe phenotypic variation explained by the putative QTL
  9. gAdditive effect. A positive value indicates that the genes derived from heat tolerance parent LA2093 contributed to increased heat tolerance, and the negative value indicates that genes originated from LA1698 reduce the effect on tomato heat tolerance
